Do not start VAZ-2106: reasons and ways to eliminate them

Every car owner who drives classic cars from AvtoVAZ constantly faces some problems. It often happens that you really need to go right now, but the car does not start. The VAZ 2106 is no exception. There are several typical reasons for this behavior. Today we will consider the main problems that can occur with the "six".

Possible malfunctions

The first thing you need to decide is whether the car worked before the malfunction and everything broke just right or the motor stopped showing signs of life after trying to repair it. If the "six" previously went well and pleased its owner, the cause of the malfunction lies in the ignition or in the fuel supply system.

Power system check

The simplest and most reliable way is to remove the air filter cover and pour about 10 ml of fuel into the carburettor. Then you need to try again to start the car. If VAZ 2106 is not started or if the engine starts and stops working immediately, then it is necessary to check the fuel supply system to the carburetor. To carry out this test, it is necessary to unscrew the screw on the yoke, which pulls the hose. The latter comes directly to the carburetor - its end is lowered into a bottle or other container. With a few taps on the fuel feed lever on the gasoline pump, you can check whether the fuel is directly supplied to the carburetor.

Gasoline pump

Before performing the test, it must be ensured that the fuel filter is installed in the vehicle. The quality of domestic gasoline is very far from ideal, so you can not do without these elements. If the pump shakes hands, fuel must move in the fuel filter. If it is dry, then experts and experienced drivers recommend looking for suction of air in the highway. This malfunction happens rarely, but it does happen. If, during the process of pressing the lever, nothing resists, then crank the engine for half the revolution.

Carburetor and fuel line

If the VAZ 2106 is not started and the fuel mixture is not supplied to the carburetor or the supply is present, but the amount of fuel is not enough to start, then the reasons are a malfunction of the main line or the gasoline pump. If the engine does not want to start up after the fuel problems are solved, it is recommended to check the carburetor. During this check, the jets and channels, and the accelerator pump are necessarily blown.

Ignition system

If after all this the VAZ 2106 is not started, the cause of the malfunctions can be in the ignition unit. In order to check the presence of a spark, remove the tip of the armored tube on the first cylinder. Then this tip is brought to the motor body by about 7-8 mm. Then start the starter and twist the crankshaft. If there is no spark, check that all important voltages are present.

Ignition coil

If after these manipulations the spark did not appear and the VAZ 2106 engine does not start, then most likely the cause is in the high-voltage ignition coil of the motor. In this case, both the coil and the wires are tested. Still often the car does not want to start because of a breakdown in the cover of the ignition distributor or in high-voltage wires. If the known good coil is not available, then the isolation of its housing from the mass will help to get out of this unpleasant situation. It is possible to hang the coil in the air so that it can not be touched by any of the nodes.

Tremblayer

If you do not start VAZ 2106, the reason can be found in the trambler, or rather in the slider. This car can behave in this way because of the breaks in the noise suppression resistance - the resistor should be searched directly in the slider. You can easily solve this problem by shorting contacts with ordinary wire. It is important to install a resistor in this place. If there are breakdowns of the slider, then to solve the problem it can also be isolated.

Do not start a VAZ 2106 car after repairs

Often, one of the reasons is the wrong timing of the ignition. The phases in the gas distribution mechanism can be knocked down. In this case, the engine may not start at all, or work intermittently - the process of the motor may be accompanied by sneezing.

For elimination, the piston of the first cylinder is placed in the upper end of the compression stroke end. It is not necessary in this case to expose it in accordance with the labels. This four-cycle unit, and the labels in it coincide two times during the cycle. There is an old but effective method - unscrew the candle of the first cylinder, and the opening is closed with a piece of rag. Then crank the crankshaft. The moment when the cork from the fabric will be pushed out, just need to be ignited.

If the phases of the gas distribution are lost, then the fault is eliminated by setting all the parameters on the factory labels.

VAZ 2106 does not start on hot

Often, the reason for this is in the carburetor. It happens that the motor is warm enough, but the needle in the float chamber is weakly held. As a result, after the motor is muffled, and the needle does not stay at a sufficient level, the gasoline pump pumps the fuel into the carburettor, which overflows. If you try to start such a car, the fuel will be too over-enriched through the carburetor. As a result, a problem arises: the VAZ 2106 is not started. This cause can be diagnosed by low engine speed. After a while, the unit starts to work normally.

Summary

There is a seasonal nature of the problem of the operation of motors. For example, in summer the car does not start because of too rich a mixture, in the winter - because of the poor. To ensure that the machine is working properly and that the owner does not rack his brains with the question "why does not start VAZ 2106", it is necessary to constantly monitor the proper operation of the carburetor and other important components. Then this classic model of "AvtoVAZ" will please its owner with stable and impeccable work.

So, we found out for what reasons the car VAZ 2106 can not be started. As you can see, all the failures can be eliminated by our own hands.
