It seems like the car is losing fire. When you get it started it runs for two or three min. and cuts off.
When you pull off the #1 spark plug wire all fire is gone away. Also hear a click from under dash board whenever it shuts down. When you unplug the idle air control valve, it runs. As soon as you plug it back up it shuts down and will not crank.

sounds like it may need a new pcm.

with it running you can try tapping on it...........if it causes a stall...............that's the culprit!
