I wonder if your intake manifold was torqued down correctly? Have you checked your oil?
Just incase your not leaking fuel from an injector line or what not.
I'm wondering if they torqued down the intake manifold properly or sealed the caps.
sounds like mine when it went into limp mode. Make sure your oil isn't over filled. Try to scan the truck with it running, my SCT didn't pull some codes unless it was running.
I'm going to guess something isn't hooked up, they missed a plug somewhere.
Did you say you can monitor fuel rail pressure?
Looks like you have no rail pressure. Might be your fuel rail pressure sensor
Under the passenger side valve cover on the fuel rail. Sensor should be like $30-40 I believe and can be done cab on
Ok. I guess turbos have to come off to access it
No, just intake and oil fill
Your KPA was at 5.1 before you got on it is the reason I think this. I would have one just incase, maybe it's just loose.
