Truck shut off while driving, trying to narrow it down
While returning from the park with family truck was nice enough to shut off and leave me on side of the road. 2003 6.0
Here is what I know:
FICM voltage is great
Truck restarted 2 hours later and immediately shut off.
I get code 2623 Injector control pressure regulator open circuit
Oil gauge does work while cranking
ICP voltage is .1 key on .3-4 while cranking
Here is where I am at.. Do I buy a new IPR? Or ICP? I am going to pull IPR tomorrow and inspect screen. But I hear ICP could be issue too...
Anyone have insight, I need this truck running.
