My 95 7.3 has 241xxx on her, and i started having the inability to start the truck warm, after looking at the fuel filter i knew i had bad injector o-rings. so this weekend i opened her up and replaced them. while dissembling it, i noticed that 3/4 of the valve cover harnesses were partially melted for the wires going to some glow plugs, because no local stores had any in stock for replacement i had to re-use them until i could get new ones ordered.

Now the truck does run and it will restart warm, but it has died out on me after driving a few times, sometimes without a restart until 10 mins later. and after it starts, about 8-10 seconds it changes from a smooth idle to very rough and the cel stays on until it is shut off and restarted. i know the valve cover harnesses are bad, but would that be the only thing that will lead to this?

Ok parts came in sooner than expected. installed & replaced wiring harnesses without any change in symptoms. i tried to unplug & run w/o the icp and it made no change. the CEL is still lighting up when the idle changes after 5-10 seconds of running. i am looking into the IPR next. i removed the fuel bowl already and the ipr looks rough.

If you want to avoid continuing to throw parts at it, get the code(s).

the IPR was broken inside, so i was looking in the right direction. after the new one comes in i will look at the codes.
