GM cars have a test lead for the fuel pump. In the case of my Sunbird it is on the driver side, under the hood back where the wiring comes through from the fuse box. It's a red wire with a terminal end. It has no power running to it at all. You plug in a 12v source and if the fuel pump comes on then you know the pump is working and the problem is elsewhere.

If you turn on the ignition key without starting the engine you should hear the fuel pump run for a few seconds. If you do not check the fuel pump fuse and replace the relay before proceeding. If the fuse is good and the relay is good then you know the pump is more than likely defective.

How do you know if your fuel pump relay is not working if it isn't can it cause flooding?
I doubt that it would be the fuel pump relay. If it's a throttle body injection vehicle, the injector could be stuck. But you wouldn't get ANY fuel into the engine if the fuel pump isn't working. Relay can be tested by turning key on but not starting. if you hear fuel pump 'HUMM', you know pump and relay are working. If no firing at keystart and experiencing flooding, not a fuel pump issue. There is a spark issue of some kind.
