Need help!! Truck is dead???
Long story short, we bought a 2010 F250 Powerstroke off of the insurance auction that was rolled by a member off of here from NY. It had a spartan tuner and also the dpf was removed etc. Anyway the truck ran good before we even repaired it, we found a cab and swapped it around using all the original interior, dash, wiring etc. We then sold the truck too a customer from WY. This all happened this spring. Anyway he drove it and put quite a few miles, took it too FL and back out west etc and he was really pleased with it. Said it got great MPG. Now he called back a month ago and said the truck is not working at all. When they turned the key the truck would not start and the dash had different readings etc.
So they took it too the dealer(no warranty of course) and first off we thought it was a bad ground and also maybe had something too do with the spartan tune. Ford reflashed the ecm back too stock just too make sure and also talked with a spartan tech and he thought it might be the PCM or the wire harness for the PCM. So they replaced that and the truck seemed too work fine for just awhile and then it started doing the same thing.
He then had the tech call me because the customer is still thinking that maybe it had something too do with the rebuild. Well it couldn't be because we used all the original wiring and there is really no way something could have gotten messed up. So we came to the conclusion it must be the ecm, so they replaced that and it still doesn't work. Sometimes the dash lights up when you turn the key and other times it doesnt.
It seems about like a dead horse but we really need too get this taken care of. The only thing I can think of is the ecm must be bad but that has been replaced so what else could cause this?? We are open too any ideas, as I will be talking too the tech in the morning.
Also Ford has flagged the vin because they have done all they can do according to the books I guess. The truck is currently at a Powerstroke specialist in FL.
Hopefully you can make sense of this story and would sure appreciate any help we can get
