I believe that I am in need of a 1991 ecu for the 3sgte For some reason the car will not start. It cranks fine and wants to turn over, but just no spark. I have taken it to 2 mechanics who say the wiring is all correct. If anyone knows what this could be please help me. I also would like to know the price of an ecu for the 91 all-trac.

Thanks so much,

What year ECU are you using right now? What is the part number?

What year celica is your wiring harness from, and who did the conversion?

What year celica is your your coil and ignitor from? What are the part numbers?

Have you tested your coil or tried a different one?

How many 3SGTE swaps have been done by the mechanics that say your wiring is correct?
