Caution: When removing the valve, be careful not to allow dirt to enter the fuel pump.
Attention! The described operation applies only to the Bosch fuel pump.
The electromagnetic engine stop valve is located at the end of the high-pressure fuel pump.
Its job is to stop the fuel supply when the ignition is turned off. If there is a break in the electrical circuit in the valve or supply wires, it will be impossible to start the engine, since fuel will not flow to the injectors. The same thing will happen if the plunger of the electromagnetic valve is jammed in the engine stop mode (the valve is closed). If the solenoid valve plunger is stuck in the open position, the engine will not stop when the ignition is turned off.
If the solenoid valve coil fails and the engine cannot be started, the following temporary repair can be made by removing the valve and reinstalling it without the plunger and spring. The engine can now be started normally and stopped using the manual engine stop lever on the high-pressure fuel pump.
Removal
1. Disconnect the negative battery terminal.
2. Remove the rubber boot, then unscrew the nut and remove the wire from the solenoid valve (indicated by the arrow).
3. Clean the area around the solenoid valve thoroughly, then unscrew and remove the solenoid valve with the O-ring.
