The fuel pump is working. It sends enough gas up to the motor, could it be the fuel injectors because when he showed me that the car was only starting with starting fluid. He started it again and held the gas pedal and it ran but as soon as he let go of the gas it stopped. Or can it be just some bad wiring?

when you first turn the key to run, (dont start it, just turn to run) can your hear the pump prime? have some one in the trunk to listen for it, it will hum for about 3 to 5 seconds.

scottydoggs the fuel pump primes and yes I can hear it. I'm going to him to test the fuel pressure.
thanks

will it stay running after it starts with starting fluid?

or does it start and stall, like it ran out of starting fluid to run on.

It will start from the starting fluid but immediately cut off.

that's exactly what I meant when I was talking about the car getting enough gas up front to the motor. That fuel rail valve you were talking about when you press to see if there's fuel. Yeah there is and a lot. It's getting a spark but won't crank over.

seams like your injectors are not firing at all.

you can take off a injector plug, use a test light to see if it flashes, or stick a side marker bulb im told works, right into the injector plug, and if it flashes its getting power. (push the metal clip in on the plug, and wiggle and pull up to take the plug off the injector)

it should flash when you first turn the key to run, and then after its running it should flash. 2 person job maybe.

thank you

Does any body have a diagram or instructions on how to get to the fuel injectors and how to test them?

Thanks dsmuts

mystic231 i'm definitely get the IAC checked because before the car finally wouldn't start, when driving and having to stop at red lights. The car would idle real low then cut off. But I am also going to check the fuel injectors too, just to make sure that their not clogged. Just to be safe and eliminate that for the check areas

I took out the IAC valve and it is covered with carbon build up. How can I check to see if it's working still, since the car won't start and can they be cleaned?

I took out the IAC valve and cleaned it With some carb & fuel injection cleaner by hand just to get off the carbon build up. The car started I let it run for about 10 - 15 minutes to let the engine warm up. That was the good news, but the RPM gauge and the speed odometer was not working. After I turned off the car it wouldn't start again, so basically I need to buy a new IAC valve and replace it?
