Check if you have a small one inch square by 12 in long relay switch bolted to the drivers side rad support with a 4 lead terminal at the bottom. If you have this, it is most likely the problem. (Get a new one $37) If you don't have that relay, check your wires are tight on the starter selenoid which is right on top the starter. Check and clean battery posts.

This car has been sitting without being started for a few months. We tried a few weeks ago to start it, but it only cranked over. Appeared not to be firing. Today using starting fluid and spraying it in the throttle body it started, but then it dies. We tried this several times. It will start then die. I see both wires have been spliced on the top on the baffle that goes to the throttle body (on the top of the baffle). I'm not sure if that is a sensor or what. I will wire it back together. I'm wondering if we have a fuel pump issue here, or the key issue where you need to turn it on for 10-15 minutes and try to restart it. The battery is weak, but I have a good snap on jumper box attached to it trying to start it. Any ideas what will keep this car running?

I have a 2003 Pontiac Sunfire. It has 130,000 Miles on it. When it starts it has been acting funny. It does not happen all of the time. Maybe 3-4 times a month. I will turn the key and it will sound like it's going to start and then it will back off and then it will start. This is the best way that I can explain it. I don't believe it is misfiring. Also, I have replaced the battery and the starter. I had the alternator and fuses checked as well. So far it has started every time but I really sounds like it isn't going to. I don't know if it is the wiring. I asked a bunch of mechanic friends if they had any idea but they don't seem to have a clue and everything they tell me sounds like bull. It was doing it before I changed my starter and then after I changed my starter it kept doing it but now it seems to be doing the same thing but sounds worse. It almost sounds like the battery starts everything but it dies before the engine can start but it keeps pushing and finally starts the car. I don't know what to do or any other way to describe it. Everything else is perfect about it. Please help me if you can. I just want to know what is wrong so that I can fix it.">

I suspected the fuel pump, and after replacing it, the car started right up. It was actually pretty easy to change out, too!

Could it possibly be your fuel pump going bad? These cars are common for fuel pumps failing. I just had to put one in a 2001 Sunfire. We could start it after spraying starting fluid in the throttle body, but it would die shortly after.

sounds like the fuel pressure regulator.its located on the fuel rail and is easy to fix.pull the vacum line off if gas comes out its bad.

I had a similar issue, and it turned out to be a loose wire in the steering column.
