what are your symptoms?
My ECU recently went on the fritz. While driving away from a stop light, truck suddenly wouldn't shift out of 2nd (mine is automatic) and the voltmeter slowly dropped to zero.
Shop determined the ECU went bad. I replaced the ECU, 2 days later the exact same thing happened. All new parts under the hood. I'm stumped.
