check and see if the pump is even turning on and if it is and still not pumping anything you might just have a bad pump.Source(s): happened to me once. I'm a mechanic.

Unplug the harness to the pump from ontop of the tank, then hook up a voltmeter and turn on the key just so that the dashboard lights up and see if you get power at all. If not, I'd start looking at the wiring harness or relay. I am assuming you've checked the fuses.

Check fuses, pump wont work if fuse is bad. should be labeled on fuse box.
