Ignition Switch OFF Engine continues to Run 24v 2001
 

I have a 2001 Cummins 2500 24v 235HP. When I shut off the Ignition the engine keeps running. Could this be the ASD? or the ignition switch? or ???..I need some troubleshooting guidence. Thanks for your help.-sam

Does this truck have any mods or changes whatsoever to the electrical wiring?

IT HAS THE EDGE COMPUTER/TUNER INSTALLED. I BOUGHT THE TRUCK WITH 121000 MILES AND IT NOW HAS 132000. I HAVE HAD NO PROBLEMS WITH THE TRUCK. OVER THE LAST MONTH I HAVE NOTICED THAT THE MOTOR TOOK A SECOND OR TWO TO SHUT DOWN AFTER CUTTING THE IGNITION SWITCH OFF. THANKS FOR THE REPLY.-SAM

I would unhook the edge and see if it continues to do it. Quick & easy to rule it out of the equasion.

Thanks for the reply. I pulled the Automatic Shutdown relay to stop the engine and removed the battery cables. The cleared up the problem for now. I am not sure if it was the ASD or the removal of power to another system that did it. :humm:

Doesnt Edge have a turbo timer???

edge has a egt turbo timer to get the egts down before shutting off. its adjustable or maybe it could be the fuel shutoff solenoid???

Put your foot on the brake while you turn your key to off .....
Mine does the same thing .... has Edge /Attitude ....it might be a safety feature.

I tried putting my foot on the brake when shutting down...no help...the problem is intermittent... and happens once out of 9 or 10 shutdowns... thanks for the input guys....

Have you tried swapping the relay with a known good relay, or just replacing it?
