Help I shut off my ISX871 and it keeps running? Now i have a check engine light after it finally stopped and i restarted it. What causes it to keep runnign with the key off? How long will it keep running once the key is off?
This was a problem for sure, guys would get killed or come close to it when transferring dump boxes. When they would hit the external ignition button to reverse the truck towards them, it would come on and squish them between the rear of the truck and the front of the transfer trailer. The key was off but the momentary switch was enough to turn fuel on. Great topic to go over because this engine is going to be around for a while.
If someone was looking at a Cummins isx or a Cummins n14 if a driver were to try to set a maintenance schedule is there a serious difference in the two engines when parts needed to be changed and service needs to be done thanks
speaking for me. I would set the N14 overhead every 250K if it were electronic. Every 100k if it were mechanical. Yes they made a mechanical N14 with a Pt pump. If it is a 525hp 1850 torque I would replace all the headgaskets at about 570K miles. If you haul heavy they wont make it past 750K. the isx can go a million with no head gasket issues. All the internals should last 1 million miles if the oil was changed at 10-12k miles religiously and the air filtering system was kept in good working order. Celect injectors only need to be set a couple times (100k and 250K) and if you set past 250k make sure you spray brake clean in the small hole on the top of the injector body so the timing plunger does not stick from oil schellack. I would not set the injector after 250k on an n14 celect or celect plus( just set valves and jakes). take off the n14 ecm and clean the back and clean the fuel cooling plate of corrosion and put some heat transfer paste on the back of the ecm and bolt it back up. They corrode and then get hot and die. You can only buy aftermarket celect and celect plus ecms now. The rest of the parts are good for a million miles I think. Turbos without vgt yes for sure but vgt you never know.
