I just bought this 2010 6.4 in Texas and drove it back to Ohio. I 'test drove' it for about 80 miles before i handed over the check. About 200 miles into the 1000 mile trek home, the CEL came on and an Auto Zone code reader showed it was a P-0088 HPFP High rail pressure. I've been chancing it and driving to and from work for two weeks now, but i need to get it figured out before i buy or pass on an H&S Mini Maxx with DPF/Cat deletes.
I have read close to 100 threads on HPFP failure and the P-0088 codes in these 6.4's, but i still have some questions for my stock truck:
1) I have 143,000 miles and have no knowledge of an extended warranty (if it is transferrable).
2) Is it best
to buy the pump (model #?) from Ford and install myself or are there better quality aftermarkets out there for the same money? I cant afford $3000+ to a dealership for their labor.
3) Is there a good way to eliminate the wiring harness or other components that are less likely to fail? I dont want to spend a fortune on the pump if thats not the culprit.
4) I see a lot of guys do the EGR delete at the same time as the HPFP r/r, is there anything else i should look at doing while i am doing this? (hoping to do it cab on but cab off if needbe. going to look at the youtube videos as some suggest).
The truck has no balls when i get on the throttle, but i can still manage 70mph interstate speeds. No hiccups, shuttering, or anything other than power loss.
To the ones that have had this replaced after warranty expiration, what kind of costs were you faced with?
Any help, advice, or comments would be greatly appreciated.
