Why does not start the WHA?

Domestic cars, however, like foreign-made cars, very often fail.

If at the right moment your vehicle does not start, then you need to figure out why the VAZ does not start.

Possible reasons

VAZ may not start for several reasons, starting with poor-quality gasoline and ending with malfunctions of the carburetor. Everything in more detail.

Low-quality gasoline

This reason is quite common, so the car repairmen recommend to refuel at proven gas stations. On poor-quality fuel you can drive some distance, but then the car can stop, and you have to clean the filters and wash the carburetor.

Lack of gasoline

Sometimes it happens that gasoline quickly ends due to the fact that somewhere there was a leakage or just the driver did not follow the fuel consumption. In this case, you need to refuel - and you can continue to move on. Many drivers of used cars complain that they simply poured gasoline if the car had been standing in one place for a long time.


Do not forget about the quality of the wiring.Sometimes, due to a small break, a car may not start, and the reason is rather difficult to find. Therefore, they suggest that you first check the wiring (ring it), as well as clean the wires (oxidation or incorrect wiring also affect the operation of the vehicle).


A dead or damaged battery can also cause the car to not start. If this is the reason, then you can replace it with a new one or connect the battery from a nearby car (that is, “light up the battery”). You must also check the wires that connect the battery.


A starter malfunction can also cause a malfunction of the machine. If you suspect that this is the reason, then before removing the starter itself, you need to check the wiring for breakages, as well as the battery charge level. Low battery charge leads to poor starter performance.

It is also worth noting that the starter anchor cannot rotate if the tips of the wires are oxidized. In this case, they must be cleaned and re-connected. There may also be an armature “to ground” closure, as well as a lever or clutch could fail - these failures can be detected by disassembling the starter.

Malfunction of pump or fuel filter

If the pump does not pump fuel, then you should pay attention to this reason. Perhaps there is a gap somewhere. Alternatively, the fuel filter may be clogged. In any case, you need to clean the filter and carefully review the pump.

Spark plug

It is worth noting that faulty spark plugs in most cases lead to problems in the engine. This may be idle, jerks, floating momentum. Candles must be removed and carefully inspected. If there are cracks, dirt or stains on the insulator, as well as black electrodes, if the thread is oily or damaged, then replace the candles. If the problem was in the spark plugs, the car should start.


Incorrect carburetor operation is probably the most common problem. In addition, there may be many faults. This can be either clogging of the nozzles, or a malfunction of one of the valves, or the air damper may not close completely before starting. One reason may be a malfunction of the diaphragm or ignition lock. If in the case of clogging the problem can be quickly eliminated by cleaning the jets, in all other cases it is necessary to remove the carburetor, look for the problem and fix it.

Ignition sensor

If your ignition sensor indicates a possible problem, then you need to figure out what this may be connected with. Maybe the light bulb is just faulty, and maybe the problem is even more serious, which can lead to the fact that the car just won't start.
