Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi there, I am Cam. What is the exact code pease, and is this the LMM or LBZ?
Ok that code is not for too low, rather too high of pressure. Is it loping at idle?Do you have a chip or programmer installed?
Do you have a scanner that will show fuel rail pressures?
Ok. Sounds good.
That does not make sense, over pressure tells me more it's not bypassing injectors. Injectors bypassing would make the overall pressure go down.
