Instructions for checking the injection system

The pressure in the fuel system is relieved by itself, without unscrewing the fuel lines, when the engine is not running for several hours.

Before repairs, adjustments and troubleshooting, it is necessary to interrogate the fault code memory unit and check the vacuum connections for tightness and the absence of air leaks.

Use only screw clamps.

For the full operation of electrical parts, a voltage of at least 11.5 V is required.

If the engine, after diagnosing repair faults or checking parts, starts only for a short time and then stalls, it may be that the immobilizer in the engine control unit is blocked. Then the self-diagnosis unit must be interrogated, if necessary, the control unit checked (in May Terskaya).
