Lada Granta will not start: possible reasons and solutions

Lada Granta is a popular and reliable car of the Russian concern AvtoVAZ, which was developed on the basis of the Lada Kalina model.

This is an inexpensive “people’s” car with front-wheel drive, which has firmly won its niche in the market. Its factory marking is VAZ 2190, serial production began in October 2011.

Technical characteristics : in terms of body type, the Lada Granta is a five-seater four-door sedan or liftback (hatchback) with an engine capacity of 1.6 liters. Manual 5 or automatic 4-speed gearbox, depending on the model.

The car is equipped with front-wheel drive, independent front and semi-independent rear suspension. Available in “standard”, “norm” and “luxury” trim levels.

The “luxury” package includes electric power steering, an ABS system, power windows, air conditioning and a modern audio system.

The disadvantage of this car is flaws in the design, not always high-quality assembly and frequent problems with starting the engine.

The starter turns, but the engine does not start

If the starter rotates after turning the key, but the engine does not want to work, then there may be enough reasons.

The first and most obvious is the lack of fuel in the car’s tank. Often the fuel level sensor lies even on new cars. It is worth checking the level in the tank and, if necessary, adding fuel. After this, you can try to start the engine. It is also worth keeping in mind that the level sensor shows an incorrect value at low air temperatures.

Timing belt, valves and damper

The gas distribution mechanism often breaks. The belt breaks only when the car is moving. Unfortunately, no one is immune from rupture, and to prevent this from happening to you, you need to pay attention to its rubbing more often and change it in time.

Sometimes the valves come into contact with the pistons and they bend. To solve this problem, you can install pistons with special grooves. Sometimes the engine does not start due to the damper being turned several teeth, in which case the sensor makes a mistake and shows the wrong phase.

To check the damper, you need to unscrew it and check that its marks match the marks on the timing belt cover. If the marks do not match, you need to turn the pulley until they match.

Battery

The starter will turn the engine even with a discharged battery. But there will be no energy to create a spark. The first step is to check the battery terminals - they may be oxidized. Even small oxide on the terminals, invisible to the eye, can cause poor starting. This phenomenon increases the connection resistance. This is very easy to check - in the place where there is poor contact, the temperature will rise.

It is usually recommended to check the negative terminal of the battery, the positive terminal of the starter, and ground on the engine. If a contact is oxidized somewhere, the connection will be hot. Most likely, this is why the Lada Granta does not start.

The battery itself may also be faulty. It is possible that when measured with a multimeter, the battery is in good working order - the multimeter shows normal voltages. But the battery capacity has been reduced and there is not enough energy to crank the starter, and the battery’s capabilities are clearly not enough to generate a spark.

correctly Light a cigarette

First of all, we must take into account that the wires for lighting should have as large a cross-section as possible. The cars are positioned with their hoods touching each other, but not each other. The positive terminals of both car batteries are connected by one wire. Another wire is connected to the minus of someone else's battery, and the other end is connected to ground.

Do not connect wires to a dead battery negative. In this way, you can charge the battery, but not start the engine, although in some cases this is enough.

If the engine does not start, connect the crocodile to the negative terminal of the dead battery directly from the negative terminal of the working battery of another car. Be careful, touching the positive one will cause a short circuit.

Once started, do not rush to remove the wires, give the engine some time. Remember. work, the negative wire is removed first, you cannot turn on the headlights, so that they are not the ones that burn out during a power surge.

Supply system

The third reason is various malfunctions related to the power supply or engine control system. For example, if any hose or unit is depressurized, the fuel pump or pressure regulator fails, the engine will not start.

Here you can no longer do without diagnostics at a service station - a thorough check of all engine systems is necessary. If a malfunction is detected, the faulty part or assembly should be replaced.

Bottom line

If the Lada Granda started and immediately stalled. The most common reasons:

1. Damage to the ignition coil connections. Needs to be repaired or replaced with new ones.
2. Low fuel pressure.
3. Poor sealing in parts of the catalytic manifold or receiver.
4. Poor performance of the engine control system.

The Lada Granda has many design flaws, but if you know all the weak points of this car, then finding the cause of the breakdown will not be difficult. Carefully monitor your car, undergo regular maintenance, replace parts in a timely manner, and the Lada Granda will serve you for many years.

Ignition system

It is also worth checking if there is a spark. If the Lada Granta does not start, then, as in old carburetor models, there is either nothing to burn or nothing to set on fire. If there is gasoline, but the car shows no signs of life, then it is worth checking the ignition coil and the entire electrical circuit that serves the coil. Perhaps a contact has oxidized somewhere and this is the reason for the missing spark. After cleaning the contact it may appear. Also, if the coil is faulty, it should be replaced.

All other reasons when the Lada Granta does not start are related to the engine itself. Often the crankshaft position sensor on Grants fails. In addition, problems may be in the circuit of this sensor.

Problems with the immobilizer (APS)

Often the Lada Granta does not start due to improper operation of the APS. If it is activated, the key is read and the engine starts. The immobilizer (APS) identifies the “native” key by reading the code from it.

If it is incorrect, then the APS blocks the operation of all vehicle systems. Here it is necessary to immediately clarify that APS is not activated upon sale in all trim levels. Lada Granta sedan is equipped with an anti-theft alarm in models 023, 024 and 050.

Lada Granta liftback in the 711, 713, 750 and 751 configurations. Many car dealers cheat when selling and say that the immobilizer cannot be activated. But by law they must do this at the request of the car owner.

If the key is not registered, the indicator lights up continuously for about 20 seconds. without blinking, and then goes out. During training, blinking occurs at a frequency of 5 Hz, at the end of training at a frequency of 10 Hz. When problems arise in the system, a sound alert is added to the light indication; it appears at the 10th and 20th second.

Decoding signals:

1 signal + flashing indicator – the code from the key cannot be read, possible reasons:

• problems in the communication coil circuit. In this case, you need to check the resistance and inspect the circuit;
• There is no transponder in the key. To eliminate the problem in the training key, you should check the presence of the transponder and its markings; if it is missing, then use a “clean” key and the CSUD to retrain the entire system;
• The transponder (located in the red key, you need to remove the red head) may be broken. In this case, for a training key, you need to retrain the system with a clean key, and for a working key with a remote control, you need to replace the remote control with a new one and train the system again;

  

  Transpoder

• Remote control "alien". In this case, you need to replace it with a clean one and retrain.

2 beeps + flashing indicator – the relationship between the APS and the ICS is broken, possible malfunctions:

• There was a communication failure on the w line. In this case, it is necessary to eliminate violations in the chain between the APS and the ICS;
• violation in the APS and KSUD chain. It is necessary to replace them one by one to identify where the malfunction occurred;
• there is no voltage on the APS and KSUD power supply. In this case, you need to check and restore the voltage.

3 beeps + intermittent indication - “foreign” key or APS. In this case, it is necessary to carry out training using a “clean” key and a “clean” KSUD. For APS, you need to configure the system using a training key native to the ICS.

4 signals + flashing indicator – the controller does not provide confirmation to start the engine. This suggests that the KSUD has already been trained with another system; it needs to be changed to a clean one and retrained.

To find out exactly the cause, it is necessary to make a diagnosis. If the controller is broken, it must be replaced and re-learned.

If there is an APS, then you need to replace it and train it along with all the working keys, since structurally in the Lada Granta the APS is located in the instrument cluster.

If there is a suspicion that the keys have been read, then retraining should also be done.

Step-by-step instructions for training the immobilizer and working keys:

• close the driver's door tightly;
• turn on the ignition using the red key;
• turn off the ignition and remove the key, the indicator flashes at a frequency of 5 Hz;
• quickly (within the next 6 seconds) turn on the ignition using the black key;
• further: we hear 3 beeps and after 6 seconds - 2 beeps;
• turn off the ignition and remove the key;
• if you need to train several more working keys, then you need to repeat steps 4 to 6 (the maximum number for training is 4 keys);
• over the next 6 seconds, turn on using the red training key;
• then: 3 beeps, after 6 seconds - 2 beeps;
• turn off the ignition, after 6 seconds we hear 1 signal;
• the indicator starts blinking very quickly (with a frequency of 10 Hz);
• turn on the ignition - we hear 3 beeps, the indicator goes out, the learning process is completed;
• turn off the ignition;
• Now you need to check the immobilizer: to do this, you need to turn on the ignition with a working or training key, if the indication does not light up, then everything went well, we try to start the engine.

Starter doesn't work

As in the case described above, the reason may be trivial. This is the battery and contacts. If the starter on your car doesn't work, you don't need to go to the store and buy a new one. Perhaps there is a bad connection somewhere. What to check and how to fix it is described above.

Another reason when the car does not work after turning the ignition key may be related to the ignition switch, or more precisely, to the contact group of the lock. Often the wires burn there or the contacts oxidize. Typically, such elements cannot be repaired, and to correct the situation it is enough to install a known good lock part.

Tips for care and maintenance of Lada Granta

• Observe the intervals for technical inspections and preventive maintenance. The manufacturer indicates a mileage of 15 - 20 thousand km;
• Buy original parts with factory catalog numbers. Do not purchase analogues of dubious origin;
• During the warranty period, get serviced at certified service stations. To a lesser extent, practice handicraft repairs in garages without providing a quality guarantee;
• A moderate, non-aggressive driving style will increase the service life of the equipment by 5 – 7 thousand km;
• Check tire pressure monthly. Follow the deadlines for switching to winter and summer tires.

Starter

If the Lada Granta does not start, the starter does not rotate, then there may be a problem with it. There may be many different interesting and not so interesting options.

The starter does not spin if the contact is broken, if the brushes are worn out, or the stator or armature is shorted. Also sometimes the cause is a malfunction of the solenoid relay. It is not capable of closing power contacts.

The first step is to check the entire electrical circuit to the starter. The wires to it are thick, at first glance they are quite normal. But inside they consist of a mass of thin veins. Over time, the wire may wear out and burn out. Often contact is broken in the terminals, which, again, at first glance, look quite normal. If the terminal to the starter has oxidized, then finding the place is quite simple - it will get very hot.

The wires are connected to the solenoid relay, and the contacts are copper bolts. Copper is highly oxidized. And if there is no quality contact, then the starter will turn, but the engine is unlikely to start. You should clean these bolts on the solenoid relay, the wire contacts and try to start the engine. If the starter is working properly, the car will start.

Solenoid relay

It also happens that suddenly the Lada Granta does not start - the retractor relay under the hood clicks and nothing happens. The fact that the relay clicks is good in itself - it means that the brushes inside the starter are in working condition. But clicks may indicate a dead battery or a faulty solenoid relay.

The pull-in relay is an electromagnet with two windings. One of them is retracting, the other is retaining. There is also a copper plate inside that closes the contacts. If the contacts inside the relay are burnt, then the resistance increases. The starter may not turn at all or may act as if the battery is dead.

If clicks are heard, but the starter does not show any signs of life, then the relay needs to be replaced. This element is practically beyond repair. Its body is flared and if it is flared, then using a regular tool in the garage it will no longer be possible to assemble the relay.

Retractor clicks may also indicate that the problem lies within the starter. So, the positive wires that are connected to the element winding burn out. There may also be clicks when the winding is shorted to the housing. To check, you will have to remove the starter, disassemble it and check it with a multimeter.

Crankshaft sensor

If the starter turns normally, the fuel pump works, the spark plugs and the “brains” are normal, you need to check the sensor. You need to look at the tachometer; if there is a failure, the revolutions are not visible.

You need to remove it and connect it to a multi-meter. You need to quickly wave a screwdriver in front of the sensor.

If there are no power surges, then it has “died” and needs to be replaced.

You can check it by testing the resistance; it should be approximately 750 Ohms.

If jumps are still observed and the resistance is normal, you need to look carefully to see if contamination has appeared and, if necessary, cleaning should be done.

Engine does not start when cold

One of the most popular reasons is a dead battery. The starter does not have enough power to spin the crankshaft to the required speed to start the engine. The battery needs to be recharged, and if it fails, it needs to be replaced.

Also, the engine will not start when cold if the seals in the fuel injectors are broken. These items need to be checked. If necessary, faulty parts need to be replaced.

Despite the fact that the Granta is a relatively new car, there are problems with compression in the combustion chambers. In this case, the Lada Granta does not start well. You can check this with a compression meter. This device is available in most auto stores. If any cylinder has less compression than required, the engine must be repaired.

The most likely reason, although not popular, is the coolant temperature sensor, which has failed. To check, install a known-good sensor.

Computer malfunction

The unit itself is very reliable and rarely fails without external intervention. But water can get on it, and this is the main reason for malfunction.

There are significant flaws in the body design; the drainage holes near the filter are often clogged with dirt and water gets into the block through them.

To do this, you need to check and clean the drainage more often. Also, water can flood the ECU after installing the alarm, when the plugs are not installed tightly or they are completely forgotten to be installed.

You can try to dry the block, but if this does not help, you will have to replace it. This problem can be partially solved by wrapping the block with film or filling it with sealant, but then this is fraught with the appearance of condensation inside the ECU.

It is not difficult to remove the ECU; it is located opposite the front passenger seat, under the glove compartment, behind the soundproofing upholstery, almost on the floor, near the passenger’s feet.

ECU removal sequence:

1. Disconnect the on-board network.
2. Remove the screw that secures the upholstery.
3. Carefully peel back the upholstery and sound insulation layer.
4. Unscrew the three nuts securing the ECU.
5. Carefully move the unit to the side and remove the two wire clamps one by one.

After unscrewing the computer, you need to disassemble it and assess the extent of the damage. We remove the board from the case and carefully inspect it. If it is partially burnt out and blackened, then nothing can be done about it; it needs to be replaced.

But if the board has no visible damage or only the output key has burned out, then in this case the key must be replaced, and the board must be washed and dried. First, you need to wipe it with a clean rag, then rinse it with WD-40 and blow it out with a compressor.

After this, rinse with alcohol several times and blow again. Now the most crucial moment is drying. Using a hair dryer set for a maximum of 1.5 hours, we blow through the board on both sides.

The engine does not start when hot

If the Lada Granta does not start well when hot, then the algorithm of actions is completely similar to the algorithm for troubleshooting when attempting a cold start.

The first reason is improper operation of the fuel supply system. The combustion chambers can be simply dry, and without fuel, as you know, not a single engine will start.

The second reason is a faulty DVT. It is also worth checking the battery terminals. Often they are not tightened as needed, but simply put on. As a result, there is no reliable contact, and the terminals oxidize. One of the original reasons is a clogged air filter.

Cigarette lighter fuse

The reasons described above are universal. Now let’s look at the specific features of the Lada Granta. This car has some interesting points. One of them leads to the Lada Granta car not starting. This is the cigarette lighter fuse. There is one for the cigarette lighter, horn and immobilizer.

Not every motorist knows this nuance. Therefore, if the car does not start, but all mechanical components are working properly, it is worth checking this particular fuse. It is quite easy to change. Therefore, you can solve the problem with the inability to start in a couple of minutes.

Bringing the car back to life

As for why a spark disappears, everything is probably very clear. Now, it would not be amiss to consider the order of her return. The reality is that in most cases, getting the spark back is a simple matter and just involves carefully checking the broken car. To be more precise, to normalize sparking it is required:

1. Firstly, check the spark on the injector using the method described above, make sure that it has disappeared, and, at least indirectly, try to determine the cause of the malfunction;
2. Next, it is enough to assess the current circumstances and act based on them. As typical situations, we suggest considering solutions to the following problems:
3. the spark plug is wet, the presence and strength of the spark are unimportant, the carbon deposits are correct (brick color) - wipe the part and screw it back in;
4. the spark plug is wet (not always) and the carbon deposits are incorrect (white or black) - clean, dry the part and try to start the engine, if there is no result, change the spark plug and deal with problems in the fuel system (cleaning the injector, checking the ECU, etc.);
5. the spark plug is wet, there is no spark at all, the color of the soot is not important - we try to change the part, if there is no result, we check the ignition system and the operation of the injector.

In principle, in theory there are no particular difficulties in repairs of this kind. Despite this, it often causes difficulties in implementation for inexperienced motorists. To solve these, you need to act in the order described above, but if something doesn’t work out, it’s better to turn to professionals at a service station. This approach to repairs will not only save time, but also guarantee trouble-free operation of the car in the future.

Perhaps this concludes the most important information on today’s issue. We hope that the material presented was useful to you and provided answers to your questions. Good luck in operating and maintaining your car!

Immobilizer

If, when you try to start the engine, a light with a key symbol flashes on the dashboard, then this indicates real problems with the immobilizer. The source of the problem must be found. The instructions contain a description of breakdowns, as well as the signals that are given in the event of a breakdown. If not, the reasons may be right here.

If you cannot start the engine even the fifth time, then it is recommended to retrain the key. But this procedure requires certain knowledge and skills. Therefore, it is better to entrust such an operation to specialists from the service station.

Main reasons

Today we will try to understand the reasons why the engine refuses to start.

The fuse for the cigarette lighter has blown

Yes, you heard right. AvtoVAZ designers are so ingenious that they installed a fuse on both the cigarette lighter, the horn, and the immobilizer. If the fuse blows, the car will not start at all.

Immobilizer operation

If the key icon flashes when you start the engine, this indicates that there are real problems. You can open the instructions and start looking for the source of the problem. There you can find a description of each breakdown, as well as the signal that corresponds to it. We are talking about the frequency of blinking of the diode.

Error U0100 “CAN bus receiver (ICE) - frequent immobilizer glitch on Grant

If the car does not start until the fourth or even fifth time, then the key may need to be retrained.

Important! Do not confuse a flashing “car with key” warning light with a constantly lit one. If after starting the engine the indicator lights up for about 10 seconds and then turns off, this means that the immobilizer on your car is not activated.

The starter doesn't turn over

Starter location under the hood

The second option would be to operate the starter. In a situation where the immobilizer does not report any problems, we may be talking about the starter. It is easy to determine this malfunction, since when you turn the key you will not hear characteristic sounds. An option for extreme sports enthusiasts, you can try closing the starter with a screwdriver. And if the starter doesn’t turn, then you shouldn’t count on the car starting either.

But the starter may not turn because the battery is discharged. You can check this if the lights on the instrument panel do not light up. Even if they are shining, you will need to turn on the high beams and see if they function normally. If the brightness is low, then such a charge may not be enough to start turning the starter.

You can view the voltage of the on-board circuit in the on-board computer. If the voltage is less than 11.4 Volts, then the starter will not have enough power to crank the engine.

The optimal solution would be to charge the battery or “light it” from someone. Let the car idle for about 10-15 minutes. This will be enough to slightly “restore” the battery power.

The starter under the hood is located at the bottom left

Problems with the starter can also have other sources, namely damaged wiring. In this case, a regular tester will come to the rescue. We connect the red contact to the starter, and the black one to the car body. The indicator should be between 12.5 and 14.5 volts. Finding the location of a breakdown can be difficult, especially in the field.

Starter crackling noise when starting

If you experience a similar situation, then removal and repair of the starter is necessary. Otherwise, you risk simply not starting next time!

Electronic control unit

Above we looked at simple reasons why the Lada Granta may not start. It is much more difficult if the electronic control unit, which is simply called the ECU, fails. People call this element “brains”.

Blowing out the candles

If you can’t start the car, and there’s a smell of gasoline coming from under the hood, then you can try blowing out the spark plugs.

In general, such an operation should be done right away, and only then check everything else. To dry and blow out the spark plugs, just press the gas pedal to the floor and turn the engine with the starter. If the engine does not start, you will have to unscrew the spark plugs and dry them.
