Ok, so about two months ago I ran out of gas in my car. Before I ran out of gas, I had no problems with it. The same night I ran out of gas, I put about $10(3 gallons) in it and it still wouldn't start, so my Dad and I thought it was the fuel pump, so after trying three different fuel pumps. Still nothing! We checked the fuses, relay, etc. When we checked the fuses there was one that was blown, which was the ECM fuse, we changed that, got a brand new relay, fuel filter, and everything. It still is not wanting to start. There is fire going to the fuel pump, but no pressure/gas going to the fuel rails. The fuel pump does not cut on, I have read online where you can leave the accessory on for about 10-20 minutes and then try to start it and it should kinda reset itself. Still nothing! I also called the 1-800 number in my owner's manual and they told me that there is no reset switch for my car, so we have came to the conclusion that it has something to do with the computer. If you guys could please help me, I would greatly appreciate it.I'm at my wits end.

Thank you in advance,
Christine Banks

What is litre size of engine? I looked at 3.1L vin j engine. What color wire at the fuel pump connector, did you check for voltage, engine cranking? Gray wire is voltage for the fuel pump motor. Solid black wire is ground. If there is a reset button on the computer itself, I'm not aware, but, take a look? Usually if you take negative battery cable loose from battery, things will reset. You need to beware it is possible that taking battery voltage from computer can cause several issues. If the ecm fuse was blown, then the computer should have been reset? Right now I'm just trying to see if fuel pump will run.
