3.1.4. Check of a power supply system of the engine

The main indicator of serviceability of a power supply system of the engine is fuel pressure in a fuel stage. But for a start we recommend to check a condition of the air filter (see. "Replacement of the filtering element of the air filter"), as this procedure is simple and will not take a lot of time. After you are convinced of purity of the air filter, check reliability of electric contacts in blocks of plaits of wires of the knots of system of injection which are responsible for fuel supply (an electrogasoline pump, nozzles).
Check of pressure of fuel in a fuel stage of the engine is possible only in the presence of the manometer with a set of adapters for connection to the fuel pipeline.
1. Include ignition and listen: within several seconds you have to hear a sound of work of an electrogasoline pump. If it it is not heard, check an electric power-supply circuit of an electrogasoline pump.

PREVENTION
Keep in mind that the electrogasoline pump does not join if in system of fuel feeding there is pressure. In other words, if you already included previously ignition and tried to launch the engine, then the serviceable electrogasoline pump had to create pressure in system and its non-inclusion in this case is not malfunction.

2. The procedure of check of pressure of fuel is described in section 5 "Engine" (see. "Check of pressure of fuel in a power supply system"). At the idling engine pressure in a fuel-supply line has to be about 3 kgfs/cm2.
The following reasons of pressure decrease are possible:
– the fuel pressure regulator is faulty. Besides, the failure of the regulator can be caused by weakening of landing of a hose on the union of the vacuum chamber of the regulator;
– the fuel filter is littered;
– the fuel pump is faulty.
Ways of elimination of these malfunctions you will find "Engine" in section 5 (see. "Engine power supply system").
