In need of a little advice on a no-start issue..

[mrc228]

Ive recently purchased an '06 F250. Its in the shop with what is looking like a bad HPOP. Ive done a little research but want to be sure I understand how the next few items all tie together and if the HPOP could have been the cause of the other issues.

Upon purchasing the truck I was told that no work had been done to the motor other than fluid/filter changes and normal "check out". I've come to find out that there were 3 injectors replaced as well as something "internal" - (service depts. description) on the turbo.

I had the truck two weeks when the engine completely lost power and started "knocking" hard as I was pulling out into traffic. I was able to limp back to the house and shut it down. I was unable to restart the engine at all. It turned over but that was it. Did some testing for obvious things.....fuel filters, diesel in the upper cup, FICM check for <47vdc (48.8 in all cases btw). Had the dealer come get it and look into it. I'm now being told that its an issue with the HPOP which is covered by the warranty.

My concern is that the injectors are fired via the high pressure oil, and the turbo bearings are cooled by the oil (not sure if its the same high pressure oil or not). If the HPOP was in the "early" stages of failing and was the cause of the bad injectors and whatever turbo part(s) that were replaced, is there anything else I can expect to be instore for, and do I need to get a more thorough diagnosis from a third party?

The dealer is also dragging its feet in a big way.. This is the second time the truck has left me on the side of the road since purchase. I noticed another poster making mention of 30 days being the extent of the lemon law returns on used cars/trucks... They want to wait until 31 days after the sell date to do anything at all.

It isnt nescarily the Hpop, it could be STC fitting, dummy plugs, ETC...

Ford isnt always the best, they told my wife she had 8 bad injectors...all 8! when it suddenly quit driving down the road, against the advice from ford, she took it to her friends shop and told him to put an HPOP in it, and 15000 miles later, injectors are fine

I agree and typically I'd do my own work but I've had the truck for literally 14 days. (At the time it failed me). This should be well within my warranty coverage and handled by the dealer in this case.

After this fiasco the truck will never go back there again. They've been trying to jerk me around for over a week now. Funny part is, I've had a few folks in my area tell me that the diesel mechanic up there is fantastic. My issues haven't been with him or the diagnostics. The issue has been the dealer trying to act in my opinion very shady about the whole thing. Went up there again this morning armed with enough documentation that they finally had to act on it with no more excuses.


I was curious about the hpop because of work previously done on the truck right before I bought it (dealer originally told me NO me no mechanical work had been done). I've been doing a huge amount of reading to the point that I am in a bit of information overload. Wanted to be sure how the parts in question interacted with one another before I made an idiot of myself.
