I own a ERF with a ism 420 engen in. It is stuck in Angola between nothing and nowere.l need help with a falt code. EDC00632-04. Truck starts and then swich of immediadly
Hi,How are you reading the fault codes, if you are using a generic reader the fault is most likely SPN 632 FMI 4.Cummins Fault code 254, Fuel stop solenoid, voltage below normal or shorted low.I do not think an ISM has an over ride screw in the stop solenoid.Attached are the troubleshooting steps click hereYou cannot run a 24 volt supply to the stop solenoid, you will create a different fault code and the engine will not start.To get you/your driver home you could take the guts out of the stop solenoid, the engine will stop on the injectors, but it will take longer for the engine to stop.Hope this helpsJohn
