    Default She'll crank, but won't fire up.

    I have a 1999 Chevy 1500 pick up w/ a 350. I've been having some starting problems. When i get in the truck to start it, it won't start. It'll crank and if i keep on cranking with maybe 30-60 second breaks then finally she'll fire up.

    Each time this happens I'll get a CEL. Each CEL is different as well. The first was a misfire, second was one telling to take it to the dealer, the third was high voltage circuit open ( every thing was still connected ). Now I have replaced the battery, ignition module, ignition coil, plugs, wires, cap, & rotor.
    My fuel pressure is at 58 psi. Now I know that 60-66 psi is said reguired but can 2 psi really make a difference.

    Also, maybe you guys can tell me if it's the pump or the regulator. Should I replace both? Can you guys tell me some tips as to tell which is bad?

    If you have spark right off the bat then the fuel pressure is the problem. Did you replace the filter?

    I had the same problem with my old 89 blazer... I replace the fuel pump and everything went back to normal.

    58 psi under what conditions: key on engine off? does it hold 58 psi while starting? If it maintains 58 psi while starting, fuel delivery would seem ok to me. Are the spark plugs "wet" after trying to start (indicating that gas is getting into the cylinders)?

    Can you post actual code numbers? my code list doesn't list a code for "high voltage circuit" or "take it to dealer"

    Yes I changed the fuel filter as well. As for the codes, I have not gotten the same code twice. I know there was one for high circuit or open circuit, the other was one that the diagnostic couldn't read. The guy who used the diagnostic told me the dealer can figure it out. He used a actron scanner.
