Check / replacement of the electromagnetic valve fuel cutoff
The solenoid valve on the high pressure fuel pump opens the fuel supply when the ignition. It should be checked if the engine does not start or continue to run after switching off the ignition. Turn on and turn off the ignition while will hear the response of the solenoid valve. If the solenoid valve does not work, voltmeter, check the voltage applied to the coil of the valve when the ignition. If there is no voltage on the circuit diagram, determine a place of breakage and repair the drive. If no problem is found, disconnect a wire and remove the valve.

Connect removing the valve to the power supply voltage of 12 V: positive wire ("+") to the valve, wire the "masses" ("-") to the valve body, and the valve stem must be drawn into the valve (Fig. 4.23). Otherwise, replace the valve. Screw the new valve with the gasket and tighten to 25 N ??? m. Attach the wire to the valve.
