prolly the level sensor, ok since the pump ecu wont ground the pump unless its supplied 7 volts from the ignition, try running your own GROUND to the fuel pump.

altight i don't have a volt meter but i stuck my test light inside the pump plug on the harness whe clip on one prong and the poker on the other and nothing. but when i put the clip on the + on the battery then touch the third prong in the plug it lights up, but that dosen't mean **** does it since both the engine and harness are grounded that just means it's making a circuit? right?
