Long story short I bought the truck and wasn’t told the whole truth on the maintenance. I was getting out in front of traffic and I sent the impeller wheel of the turbo through the intercooler and into the motor. So with almost 300k on the clock we decied to rebuild it. Studded everything in it on the build.
Rebuilt the motor my self(went to a cat specific tech school). Everything on the motor side is fine im fighting the computer or some kind of wireing.
You can start the truck in the morning and it won’t run right it coughs and it’s throwing 14 or so codes im not 100% sure on the numbers but it’s throwing a 2 codes for the throttle positioner, codes for the map sensor and ambient air temp sensor, bank one high/low fault, code for the cam sensor(has been changed today) I also keep getting the water in fuel light coming on no matter how much I drain separator.
You can unhook the fuel rail sensor and the truck will for to full rail pressure and will not drop off it stays about 27,000 and the idle smooths out and it dosent go up and down. When you hook rail pressure sensor back up the idle will climb and fall and most times when it falls rail pressure is 1900 and the truck dies.
At a loss with this truck have tried so many things and it’s not getting me any where any help would be much appreciated
