WARNING: This page is about a different car, the 1983 Volkswagen Vanagon, 1983 Volkswagen Rabbit, 1983 Volkswagen Quantum, 1983 Volkswagen Pickup, and 1983 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
If fuel cut-off solenoid valve fails, engine will not shut off with key. Before replacing fuel cut-off solenoid, it should be removed from the injection pump and cleaned. See Fig 1 .
When the solenoid and plunger are clean, the plunger must be checked for free movement in solenoid. Install solenoid in pump with a new seal. Test for proper solenoid operation by connecting to and disconnecting from battery voltage.
A manual fuel cut-off has been added to the injection pump. If the engine continues to run after key is turned off, move lever in direction of arrow. See Fig 2 or Fig 3 .
