New Delco fuel pump 63 lb pressure. new fuel filter, new pressure regulator, new computer, new mass air flow, new plugs, wires, cap, rotor, cam shaft pos. sensor, crank shaft pos. sensor, EGR valve. new coil & module, air temp sensor, throtle body pos. sensor.
The only time it will start is w hen I pour fuel into the throttle body. It will start, but quits when the fuel is gone.
What could it be ?

Sounds as if you have no injector pulse. I'm sure you've check fuses? Should be two for PCM. Using a noid light, have you checked injector pulse?
