Installed new fuel pump, new fuel filter, new spark plugs,new coil packs, new cts, crank sensor is good.fuses are good relays are good.I jumped the fuel pump relay and it pumps fuel but will not work when key is cycled on.throttle body clicks when key is on it is clean also.was running fine then had this issue. Got it running again and the gas pedal was touchy like if u accel too fast it would die or if you acceled slowly then let off gas too fast it died real smoothly. Now just cranks and throttle clicks and no fuel pressure. Fuel pump and coils are ac delco. Plugs are gapped correctly. Tried a scanner it couldnt communicate.
