92 1500 5.7 While driving the truck just died, no warning, no engine codes... Things that were replaced... Fuel pump, fuel filter, cap, rotor, plugs, wires, pcv valve, throttle body gaskets. Before the fuel pump was replaced the truck had no power, and would die when you hit the gas from a standstill. But now it's fine, and the only thing is before it's warmed up it slightly backfires, and the one time it died when already warmed up. It started right back up, and drove fine. It slightly lacks power for the first gear at the first couple of seconds when flooring it. Any ideas would be appreciated.
