Hello All,
I have a 78 C10 longbed with a 454, edlebrock intake, Holley 4 barrel, MSD ignition kit and she won’t run. I’ve changed both tanks, fuel sending units, fuel pump, alternator, coil, ignition switch, battery, battery cables, oil, transmission fluid, had the carb rebuilt and changed breaks and break lines just because. When I put the new fuel pump on it started right up and idled well for about two weeks. I put it in drive or give it gas and it died. Now it won’t start at all WTH? I did notice that when it was running it was making a high pitched sqeeking noise but if I remove the negative battery cable the whole it’s running the noise stopped. I don’t know if one has anything to do with the other but...
