What PID criteria do you look at when faced with a no start/cranks good Duramax (LLY in this case)?I am currently looking at a cranks/no start with good primer pressure, but with only 1 mpa of fuel pressure during cranking and no fuel from the fuel pressure relief valve. I would like to know what other PID's can be helpful in zeroing in on a fault.
