03, No start, ICP low, dies when brake applied
03, 200k miles, truck never died while driving just simply quit starting, give it a little shot of starting fluid and it will start after a bit of cranking, got an ICP circuit signal fault, noticed of the scan tool the desired ICP and actual were good, although zero voltage from the ICP, i pulled the wires from the IPR and noticed the casing from the two wires where pulled out of the pig tail and they were actually twisted making contact with each other,
while messing with that plug to the IPR the ICP plug popped with no effort at all so i made the assumption that it wasnt plugged in properly and was not latched,
So i shrinked the wires on the IPR harness and re-installed both plugs making sure the ICP plug snapped correctly into place, still no start without starting fluid,
got the truck running again and watched the scan tool while running to monitor the ICP and desired value and actual value were always within a few PSI of each other, so i assume thats all good, ICP voltage had a range from .98 to 1.15v and would peak at about 1.25v when accelerator applied,
truck sat and idled ran through self test a few times, revved it up to 3500rpm held just fine, stalled it up to 2000rpm and held just fine, but if you press and hold the brake pedal at idle the truck will surge untill it dies, if you left off soon enough it will recover but if you hold the brake pedal it will die,
still has p2285 low ICP circuit and p2291 low ICP while cranking, theres also a fan circuit signal fault, water in fuel, think thats it.
for the record this is a buddies truck! I dont believe he knows much about maintenance on a diesel, he just changes the oil and drives it, usually hauling horses long distance.. any ideas? thanks!
