Re: 2000 grand prix noisy fuel pump?

The 2000 GTP has a two speed pump, so you you may be hearing the "noisy" pump when it is in high speed mode. It usually goes into high speed mode when the car is initially started and for high boost/ high throttle. Unless you have a drivability issue, stalling, lack of power, random missfire, I would not worry about it.
