So I have a '91 Si and my ECU is fine but a buddy of mine has a CRX Si and he's been having trouble getting his to start. He went through all the spark, fuel even put a good Main Fuel Relay in and still it just cranks. So he thinks its his ECU and he asked if I'd try it in my CRX Si and it did the same thing to mine...it just cranked and wouldn't start. So what would cause this inside the ECU? A bad transistor, chip or solder needs redone? Can it be fixed easily? If so who does that kind of work?
