1990 7.3 ford diesel wont shut down
You need to determine if the problem is in the ignition switch or the fuel shut off solenoid in the Injector pump. As you stand in front of the truck facing the engine, the wire that goes to the FRONT connector on the DRIVERS side top of the injector pump will be the shut off solenoid.
turn the key to "run" and then disconeect that wire, if it "clicks' then the problem is most likely the ignition switch. If it doesn't then run a jumper wire from the positive post of a bettery to the connection. If it clicks then the problem is the ignition switch, If it doesn't, then the solenoid has failed. the fuel shut off solenoid is available and not hard to change. Just be sure to pay attention to to the spring and how it is assembled. You can purchase the fuel shut off solenoid from mid west fuel injection, there may be other places but I know they have it. Ignition switch should be available form most any auot parts store.
