[almightyone]

the engine will spin over all day and it will run of starting fluid but the pumps wont kick on with the key i have replaced the ignition switch and the fuel pump relay i was told the anti theft system burnt up i was wanting to bypass it

Disconnect your fuel supply pump (in trunk under metal plate) and run a hose to a gas can. Disconnect the ignition from the solonoid so it won't spin the engine. Turn the key and see if the supply pump is working. If not, it won't get enough fuel to the fuel pump. There is a rather wierd connector between the pump and the top of the pump assembly where your fuel lines connect. The connector will disentagrate and the fuel flows from the pump back into the tank.

You need to get a wiring diagram and trace it out. Start at the pump and see it it is getting power. I had a similar problem with my 89 gli where the fuse kept popping. The problem turned out to be my O2 sensor wires shorting on the cat. They shared a common hot.
