Hello. I'm in need of some help. I do most of the work on my Fiero myself...but I'm not expert. I have a 1984 Fiero that has been in a heated garage and not driven in about two years. I went to start it and it cranks but will not start. Starter fluid in the throttle body will run the car for a few seconds. I've changed the fuel filter (which was dry when I took it off). Still no start.. I changed the fuel pump relay, thinking that was the problem. Still no start. I changed the ECM, still no start (I don't think the old one was bad). So I thought it was the fuel pump, so I dropped the tank and put a new pump in. The old pump had the red wire disconnected and the rubber hose had come off the connectors. So I thought for sure that this would fix the problem. STILL NO START. I do get a code 12 when I use the test connector, but not other trouble codes. I ran 12v lead to the fuel pump test terminal and still don't get any fuel (I can't really hear the fuel pump running). I have not been able to trace the entire leads from the gas tank to the engine, so I'm not completely sure everything is connected. On an 1984 is there a connector somewhere near the catalytic converter? Is there any other way to test the leads to the tank without dropping it again? That was a very difficult job and I'm not looking forward to doing it again. Would another problem prevent the fuel pump from running, like fuel pressure, etc? One last question, when I replaced the pump the pump had different electrical connections. The old pump had three wires. A red and a black from the sending unit and another black that grounded the pump.. The new pump had only two wires, a red and a black, which I connected to the sending leads per the instructions. I'm assuming that is correct. I'm frustrated with this problem and hoping someone can help.

You can jumper the pump on the ALDL terminal G. Use 12v from the cig lighter

I tried that and didn't seem to get any fuel or hear the pump running.

My 84 did the same thing when I got it. The hose inside the tank had dissolved at the pump. Does sound like your pump is trashed.

The old pump was trashed, the red wire had come off and the rubber hose definitely shot. But I replaced the pump and all parts. So unless the fiero store sent me a bad 'new' pump, that shouldn't be the problem.
