Hi Tim, My name is***** will be glad to try to help. Check the fuel shutoff solenoid and linkage at the injection pump to see if the linkage is actually moving with key on and key off. If not, test for power both ley on and key off at the solenoid to confirm power on and off and if ok but the solenoid is not responding, replace the failed solenoid if the linkage checks ok and you can shut it down manually moving the linkage.
