Turn the ignition on without starting the vehicle. You should hear the pump run for a few seconds and then shut down. You may have to listen at the fuel filler door with cap off and a helper to hear it. It you hear nothing then check the fuse and fuel pump relay. If they are good then the pump is more than likely bad. I all seems well, then a fuel pressure test run at the fuel rail will verify the condition of the pump and if it is putting out enough pressure.

Assuming its Fuel injected. check the FUEL pump, or the fuel pump relay. there is also a fuel pump fuse under the hood you might check that first. Your problem is most likely a bad fuel pump. If its carburated check the fuel pump or a plugged fuel filer.
