npt working

Check fuel pump relay and also check the fuel pressure regulator. Disconnect FPR vacuum line, if gas is present, the FPR diaphram is ruptured.

Do you have a security light on?

I swapped the 2 relays and there was not any change. There is not a security light on. I jumped the fuel pump and the car runs fine, but there is still no power to the plug for the pump. I only have the power for the 3 second primes.

If you jumped the pump to run off battery voltage and it runs fine, then the pump is OK.

The problem lies in the pump wiring harness, or oil pressure sending unit which serves as a backup to the FP relay.

The oil pump sending unit is designed as a backup to FP relay, but not designed to run pump all the time.

I would replace the OP sender, if problem persists, then you will have to get into the harness and check for open/shorted wires.

after checking the pump and testing several sensors found a ressistor in the right side in the wheel well above the washer fluid bottle was bad. GM has a updated part and location for this ressistor. the way i think this system works is full power, batt voltage to the pump on the prime and when the boost reaches a set level in the computer. all other time the sytem run on a lower voltage when the deman for fuel is lowwer.

Generally on supercharged engines, as vacuum goes to boost, the fuel pressure increases as well as injector pulse width.

Air/fuel ratio goes to 12.5:1 or alittle lower to prevent a lean condition.

A lean condition on a super/turbo/nitrous is an immediate burnt piston as combustion temps skyrocket.

then what would be the reason to ad a resistor to the fuel pump feed during normal operation.

Less resistance would increase voltage, more would decrease.

Like LED bulbs, a resistor is added inline on a non LED light circuit to reduce voltage in order not to blow a fuse, since LED's require much less voltage than incandesent.
