Chit!!! I'm not a spiritual man but this morning I had a vision of me cussing this truck! Turbo on, ran the truck and it fell on its face.
Pinout data on the truck in hand I went to inspecting the data I received and I have some crazy stuff going on.
99% engine load,
2.8v ICP sensor,
FICM sync'd 48.5v w/13.5v
EBP @ 55 psi (with the new and old turbo and exhaust removed in front of Cat)
ICP @ 2800 ish psi actual (dies with the ICP sensor disconnected too)
MAF out of pinout values
Baro out of pinout values
etc....... All of these values are showing right about the time the truck is dying.
I'm looking for key on, @ idle, and @ high idle values. Never really gets to the high idle
I'm not broken yet but this truck went to the dealership to get it on the IDS (via nice tow rope
) I had turned the key on with the IPR, and the FICM disconnected before I had installed the turbo and we had some memory codes. Didn't clear them before the trip to the dealership.
Got a call an hour later stating that the FICM was bad for sure and I had em replace it. Went to pickup the truck and after conversating with the service writer (know him pretty well) I went to drive the truck out of the service bay and it dies the same way it did before. Turns out they didn't test drive the truck and just used the memory codes to diag the FICM. That overly-priced component will be going back. More diag time on monday.
I know it's hard to diagnose a problem like this on a forum, but my co-workers are tired of talking powerstroke with me and I just need a place to vent
I'm surely enjoying all of the advice as it gives me hope that the damn thing will run again.
