Car starts, then dies.


I have a 99 GT that will only start if I floor it and when I let off the gas it dies. I kept my foot on the gas until the motor was completely warmed up thinking that it was just cold because it has been below zero here for about four days. Today it was about 10 outside and the car sits outside. The car has never had an issue starting in cold weather in the past, this just started. I disconnected the battery for about ten minutes as I pulled the sensors out of the intake think the computer needed to be reset but that didn't help. I spoke with a mechanic and he thought it was the fuel pump or an intake sensor on top of the intake manifold. He said it would run about $500 for the pump and installation. How hard are fuel pumps to install in this car, because I may try that myself. The only thing that is holding me back is that if it's not the pump I'm out $150 for the part and back to square one. Anyone have any advice or thoughts on what could be happening?

You can get a svt focus pump for about $100. Putting it in doesnt take much. If that isnt your problem well atleast you now have an upgraded fuel pump rather than buying the one thats already in there.

Problem solved.....for now, lol. After reading the thread you posted I went outside and unplugged the iac, cleaned it out and plugged it back in and the car fired up immediately and idles perfectly. Thanks again, this site is full of knowledgeable and helpful people.
