The 2002 Pontiac Grand Prix GTP doesn't have a dedicated fuel pump resistor in the same way some older vehicles did. The fuel pump's operation is controlled by the PCM (Powertrain Control Module) which manages the voltage and current delivered to the pump electronically. There's no separate resistor component to adjust the voltage.
If you're having fuel pump issues, the problem is likely within the PCM, wiring harness, the fuel pump itself, the fuel pump relay (if it uses one, though it likely uses PCM control directly), or a faulty fuel pump inertia switch. You won't find a standalone resistor to replace.
