Argh!! Why Won't It Start?

[1989GT]

Alright man this may not be your problem but something to think about. A few years back I was having the same problem as you. It turned out to be a wire at the starter relay was broken at the connector. It looked like everything was fine but the wire was broken. I had spark at the plugs, the car would turn over..but the fuel pump wouldn't turn on. So I hard-wired the fuel pump and it still wouldn't start. So I started chasing wires. And that's what I found. I can't remember what exactly the wire does now. But I know that it sends a signal to the EEC. And that goes to the fuel pump. What's weird is that even with the fuel but running it still wouldn't start. Gotta love computers. I know there's also some fusable links in that wiring too so you might want to check those out. I did all the wire shooting with a haynes manual. Hope this helps man! Good luck.
