I will hook the pump up to the battery to see if it runs. Is it possible for the pump to run but not put out enough pressure? I read some where that some injectors won't spray if they don't have enough pressure.

I did not replace the injector clips. Do parts stores have those or are they a special order item?

I did put in new injectors about a year before this happened. They were kind of spendy so I hope they don't have to be replaced. I did replace the fuel relay that is above the ECU so that is new. I will hook the old pump up to the test connector under the hood and see if it works there. I figured when you turn the key on there would be power at the pump so that's good to know that it has to be crancking. I have to admit that I'm a little lost when it comes to computerized engines. I come from the 60's muscle car era that just had fuel and spark so they were much easier to diagnose. I will check the things that you guys listed. Thanks, Is there a way to test the "knock" box?

Hi, I am relatively new to your site. I have a 1986 Starion that won't start. Here's a little back ground; I had replaced the head with a much better after market head from Top-End Performance about a year and a half ago. I had put about 50 miles on the car and one day while it was idling to warm it up to go for a drive it just quit. I tried to start it and it turned over but would not start. It had spark so I figured it was the fuel pump I replaced the fuel pump but it still would not start. I checked the power back at the fuel pump connecter but there was no power when you turn the key on. I did some checking online and figured it was either the ECU or the fuel pump relay. I replaced the relay since that was $85 and that was cheaper than an ECU which was around a thousand dollars. Still no power back at the connector. I did not have the money to buy an ECU so the car sat for about a year until I ran across a guy that wanted to buy the car and said that he had a good ECU. We put his ECU in but it still would not start. So I'm wondering if his ECU was really good or if there is something else causing the problem like a wire running back to the fuel pump. Any ideas?
