84 Mercedes 300D turbo diesel problems with engine it's running after ignition switch is turned off?
Technically, a diesel engine does not need any outside electrical source to keep it running. Injectors are mechanical and keep running until they are forced off, usually by a solenoid. Check the shutoff mechanism to make sure it isn't sticking. This diesel shuts off using vacuum. If your vacuum is low or leaking, the vehicle will not shut off using the key. You have to open the hood and push the SHUT OFF plate near the top of the engine in the fuel linkage. Vacuum leaks are common and will keep the door locks, climate control, and engine shut off from working. The shut off valve, located on the back of the injection pump, can fail. It is vacuum operated and the diaphragm can tear. Vacuum test this valve. If it holds vacuum keep looking for other vacuum leaks, if it leaks replace it.
