I am unsure if my fuel pump is out or if the fuel filter is clogged how can I tell?
If you hear the fuel pump running, then start by replacing the fuel filter. If you don't hear the pump, check the fuse. A fuel pressure test will verify if the pump is good or not. It can also be a fuel pump relay or in rare instances a defective ECU.

Is your fuel pump running? Turn the ignition on without starting the engine. You should hear the pump run for a few seconds. If not, then check the fuel pump fuse and relay. If it is running and no fuel, replace the fuel filter. If the fuse and relay are good, and the pump is not running, the pump is bad.
How do you tell if your fuel pump is bad on your 2004 Pontiac grandam gt?
You first need to see if the fuel pump is actually running. In order to do this you will need a helper. Open the fuel filler door and remove the fuel cap. Have your helper turn the ignition on without starting the engine while you listen at the fuel filler door. You should hear the fuel pump run for a few seconds then shut down. If you hear the pump running this tells you the fuse and relay are good. If the pump does not run check the fuse for the pump and fuel pump relay. Even if you hear the fuel pump running this does not mean is actually pumping fuel. The only way to test this is to perform a fuel pump pressure test at the fuel rail. Make sure to replace the fuel filter in either case.

Of course if the fuel pump is not running the fuel pump fuse, fuel pump relay, or the pump itself is defective. But the pump can be running and still be not pumping fuel. The only way to know for sure is to run a fuel pressure test. Do not overlook the fuel filter as it may be clogged.
