There have been some isolated instances of issues with the existing fuel injection pump stop solenoid (1). The issues with the fuel injection pump stop solenoid have caused issues with starting the engine and fuel leaks.

A new fuel injection pump stop solenoid (2) has been introduced. The improved fuel injection pump stop solenoid will offer better reliability and extended service life.

The part number for the fuel injection pump stop solenoid has not changed.

Follow step 1 through to step 7 for the correct procedure to replace the fuel injection pump stop solenoid.

1. Turn the battery disconnect switch to the OFF position.

2. Disconnect the electrical connection from the fuel injection pump stop solenoid.

3. Remove the existing fuel injection pump stop solenoid.

4. Install the new fuel injection pump stop solenoid. Tighten the fuel injection pump stop solenoid to a torque of 15 N·m (133 lb in).

5. Remove the protective cap.

6. Connect the electrical connection to the fuel injection pump stop solenoid.

7. Turn the battery disconnect switch to the ON position.
