How do you know if your fuel pump is not working on a 1999 grand am?

Remove the gas cap and listen at that location while someone turns on the ignition without starting the engine. The pump will come on and run for a few seconds then shut off. If you cannot hear it then it is not running. Check fuse, and relay before assuming it is defective.
