Oh, well that's not your problem then. Switch the wires around then. Are you sure your firing order is correct?

Man, It sounds like some of your wiring is goofy. Is everything grounded etc etc? Will it rev out any? What are all the codes you were getting before switching around the wires? Did you check to see if any of the ECU wiring has came apart?

Ok,

first, you need to reverse the outside wires on your TPS csensor if it has not already been done.

before:
( X o Y )

after:
( Y o X )

Next, get a multimeter and make sure your wiring is right. Your IAT signal wire is pin C5 on your ecu; check for continuity in the wires and make sure it is in the right place.

Check your compression btw.

A motor will fire with 3 things; fuel, spark, and compression. If you have a sufficient amount of all 3 you will get combustion. Not saying it will run like a champ, but if it is not turning over you are lacking in at least one of these areas. GUARANTEED every time.

As for your car not running unless you put your foot on the gas, that could be MAP, the IAT sensor will cause the idle to surge, but not studder and shut off. That sounds like MAP.

GL gettin it all right. PM if you have any ?'s
