Re: Oldsmobile Trofeo Trouble

I forgot to mention everything is new all new injectors, rail, etc. and i've done all that using a noid light. I have two alternators, went to the parts store and tested it on the bench. it was good then i tested the one on the car, it was bad, went home and switched them and tested them again, this time the one that was bad on the car was good off of it and the good was bad. I ripped out the replacement ecm and put a new one in now it runs great but i still don't have any gauges unless i turn on the lights then the radio backlight goes out, i still have error codes 41 and 47, I replaced the ignition module, but that didn't change anything. pretty much i've been really busy today doing this. I've done every diagnostic and repair i can think of. Nothing seems to get it done. Maybe the body control module?
