Starting/Fuel? problem!
I figured i'd try and post for help, even though i understand it may be difficult not seeing the car itself. I thought my car not starting was due to the fuel pump. However after just replacing it (the hard way) it still has not started. The fuel filter is new, so i'm stuck on what it could be next. The engine wants to turn over, alternator is fine, which makes me believe it is something with the fuel.
It is building pressure for sure... but it just keeps sputting...Last edited by UC Warrior 1; 04-27-2009 at 09:21 AM.

Well it isn't any fuses, they're all good. I dont have a pressure gauge to check the pressure.

if you got fuel my next check would be spark. At least when I had my Grand Am that was second. A couple coil packs went bad. I had to check each wire. Hell the facorty plug wires went bad at 29k.

Ok so an update...(god this is fun)
The car is now getting the correct fuel pressure, new filter, pump, and it was starting before i put in a new filter, however, now i think it's just flooded. if not i dont know what else it could be. There is spark on everything so.. >.>

Pull a plug and see what it looks like. could also be the cam or crank position sensor. What is your security light doing?

The security light acts as normal. It is on when the key is turned halfway and turns off. I'm only assuming the pressure is correct because there was no fuel coming out of the valve when i started, and now there is.
So ya..really running out of ideas. It's still starting (if i move the key back and forth a few times) and lasting a second or two but just doesn't stick...

get a fuel pressure gauge as well, then we can really dial in what it happening, fuel at the shrader valve just says you are getting fuel, not how much pressure is there. HAve you trieed metering the continutiy of the fuses under the hood?

No but i did switch out the fuel pumps 2 fuses, no changes. Ill also get a fuel pressure gauge. Leaving in 5 min... Hopefully something comes up. If i'm not getting the pressure, then what can it be? I dont even know how you clean dirty lines... (such a novice, but only one way to learn..)
