Examination
Turn the ignition on and off several times. In this case, the solenoid valve should click loudly enough.
If it doesn't, disconnect the wire. Using an auxiliary wire, connect the valve to the positive terminal of the battery.
If the valve clicks, check the voltage supply according to the diagram and, if necessary, replace the wires or parts. If no faults are found, replace the fuel cutoff valve.
Observe cleanliness and safety regulations when working on the injection system.
Withdrawal
After disconnecting the wire, unscrew the cut-off device (1).
Installation
Remove the piston and solenoid valve spring and insert them into the new device. Pay attention to the correct installation of the sealing ring.
Screw in the new shut-off device and tighten to 20 Nm. Install the wire.
