help...weird problem after hpop and egr repair
Truck has run flawlessly up until this repair.
I was experiencing no start when hot problems. The EGR cooler was also slightly leaking.
I have an experienced diesel mechanic doing the work. He has worked on 6.0's extensively and he is now stumped. He has performed these specific repairs many times, so it isn't like he's digging into new territory.
The cause of the no start when warm issue was the dummy plugs and stand pipe O rings. They have been replaced. The STC fitting was not leaking at all, but a new oil cooler with the updated fitting has been installed. He also removed and cleaned the injectors, replaced with new O rings. Deleted the EGR as well as cleaning the intake.
Once reassembled the truck wouldn't start.
Diagnosis pointed to the HPOP. HPOP was replaced.
Tried to crank again. Got the truck running. After roughly 20 minutes the truck died when he tried to up the idle.
Diagnosis says the IPR was not functioning properly. Replaced the IPR.
Got the truck cranked again, she's running beautifuly. After 45 minutes she shuts off on her own.
Codes P2614/P2617 popped up. Apparently that isn't uncommon after a stall....
She will not start at all.
Since then I've been going up to the shop trying to see if I can somehow figure out how to help.
FICM is fine. IPR is fine. Put shop air onto HPO system to see if there was another leak. Not a single bit of air can be heard, ramped up the IPR and still no air. System should be fine.
ICP is reading no pressure (i think I'm wording that right).
WHEN TURNING THE KEY ON, THE OIL PRESSURE GAUGE READS MID WAYS....... This seems odd to me....
Other than checking the PCM harness, I and the mechanic are stumped. He has calls into friends that work at the local dealership hoping to get pointed in the right direction.
Any of the Master Techs/Experienced guys care to chime in? Any input is greatly appreciated!
