I have a 1996 Ford Taurus (3.0L) that I just put a different engine in. The engine is the same type as one that came out of the car and runs fine. The service engine soon light is on and the OBDII scanner says it can not establish communications with the car. Is this a problem with the ECM not matching the engine? I understand some vehicles require a new control module whenever an engine is changed.
have the same problem?
