I'm having a 93 notch built for someone for a Christmas present. Everything is almost complete, however there's something going on electrically that keeps rearing its ugly head.
I drove the car to the builders, ran fine. Upon tear down, numerous wire splices were found, wires cut and dangling, etc. The builder rewired things the correct way...he said, and I trust his word. However, when firing up for the first time after complete rebuild or motor and trans, the car ran rough for a short period of time and the died. At this point it would noit crank back up. Builder said the ecm was bad original (A9L), put another known good a9l in and wouldn't work. For giggles he put in a A9P that he had a the car ran fine. This is a five speed car, all the research I've done says in a straight drive car either ecm's will work. So I figured for what ever reason my original ecm went bad, and the ones the builder had a9l's were bad to start with. So I bought another good a9l and installed, still ran like ....put the a9p back in, runs good.
Why aren't the a9l's working ?
