Tom Bothe,

blackmercedes is right. You should look for a vacuum leak as vacuum is used to shut the fuel supply off and shut down the engine. When the circuit with the shut down actuator in it loses vacuum due to a leak in one of the connectors, or the diaphragm actuator that actually moves the fuel shut off lever ruptures and leaks, the car will stay on when you turn the key off and take it out. You have to use the manual shutoff lever on the injection pump to shut the car off, or stall it if you have a manual transmission.

Post your question or problem in the Diesel Discussion group, or do a search as this is a common ailment. If you are having a different problem some of the guys on that board should be able to help. Jim
