ECU Equestion
 

1. Could you tell me if there is a way to determine if my ECU is working?


2. The spark plug coil system (if thats what its called). In order for it to work correctly all 6 plugs should be connected and should there be any other wire connected to it , going to the alternator. I'm learning and not a mechanic at all. I bought this car from a guy who was working on it and i don't know where he left off. He is helpful.

can you take pics?

what year is your supra?
