no power for pump and no injector pulse I have an 03? ls4 5.3 custom harness built by a guy who will not answer his phone. It has a blue connector and a green connector with a factory ECU. 5 wires left loose, a blue one(key on) gray(fuel pump) white(tach) Brown(MIL) purple(brake input-TCC) I have 56 lbs of fule in the fuel rail and if I put starter fluid into the trottle body it will fire for a moment. There is no power coming from the puel pump lead so I wired the pump to the ignition.....and there seems to be no injector pulse.....any help out there?
I had to do a pinout to see what these wires were for.
