How many different reasons are there for which «Friend» does not start or does not want to take you further, no one has yet considered. And the most annoying thing is if it is on the way and a couple of tens of kilometers are left to the parking lot.
You should always start looking for the cause with the power of the car. Find out if it is in the gas tank: instrument readings can fail. There is a special well in the tank, in which the fuel pump is located, without gasoline it should not work. On «top ten» it's bad when the tank is full, and it's bad when it's empty, fill up with gasoline more often. To increase the reliability of the fuel pump, there are special additives that improve its performance. By the noise under the rear seat, you can determine whether the pump is working or not.
First check the fuse in the fuel injection system. If it does not work, go to the power supply of the electric fuel pump. Next to the fuel pump there is a block with a positive drive for heating the rear window. By connecting this drive, you are finally convinced whether the fuel pump is working or not.
To make sure that the fuel system is malfunctioning, you need to slightly open the throttle and pour a little gasoline into the intake manifold. Turn on the ignition and starter. If the engine sneezes or starts. The fuel supply system is OK. But you need to pour in a little gasoline; if the system has a neutralizer, it can also fail. After its failure, the engine often loses power and stops. Then the engine may start working for an indefinite time, but when starting off or stalling itself again. If you need to go, loosen the clamp in front of the converter, allow the exhaust gases to escape.
Faulty sensors and other elements of the power system that affect operation will be discussed in the next section, but you can ride with faulty sensors. Only faulty speed sensor (provisions) crankshaft failure stops the engine.
The ignition system unit works reliably, and if only one candle is not energized, it will triple and you can go. If the entire unit fails, the engine shuts down instantly.
