Simple put your thumb overtthe end of the fuel hose to see if there is any pressure in the line. You can also blow on the end of the fuel line and see if you can hear any bubbles in the tank also make sure that the car is not parked on an up hill slant.

Go to the wiring harness where it plugs into the tank and find the gray wire. Hook up a testlight or voltmeter and have someone turn the key on. You should see voltage for the first 3 seconds only and then it shuts off. If you are getting this power signal and can't hear the pump starting, you have a bad pump.
