everything is wired all sensors work. I put the 2000 ls ecu and car won't start. I have experience in pinning the ecu plugs done it in many other swaps. If anyone knows what to do please help. It's my friends car. I am trying to get him to get a conversoin harness. he just isn't listening. thanks

 

The ecu you have has an immobilzer built in and wont start since its not in the car it came out of. I would just use the EX ecu and would add an adjustable fuel regulator.
