Installation steps (typical for stop solenoid):

1. Disconnect battery negative cable
2. Locate the stop solenoid on the injection pump (usually near the fuel inlet or on top of the pump)
3. Disconnect the electrical connector
4. Unscrew the old solenoid from the pump body (catch any fuel spill)
5. Compare new solenoid with old - check thread size and plunger length
6. Apply thread sealant to the new solenoid (if not pre-coated)
7. Screw the new solenoid into the pump, tighten to specification (typically 20-30 Nm)
8. Reconnect the electrical connector
9. Reconnect battery
10. Turn key to ON (but do not start) - you should hear a click (plunger retracting). Then start engine and verify proper shutdown
