Welcome to AF!!

The first thing to do is to see if you have the basics. Fuel and spark without either one the engine will not start. If you have no fuel check the fuel system ie fuel pump, fuel pump relay, fuel pressure regulator and injectors. This also includes the ECM. If you have fuel then spark is next. I suspect the ignition module may be bad and not producing a spark. This could also be a coil issue.

Another common issue on your year Grand Prix is a failed ECM. The OEM part#1227727 is known for premature failure, mostly due to being mounted under the hood and exposed to the elements. They can and will work intermittently before failing completely.
