Obdii Pcm?
Obdii Pcm?
Anyone got one for a 6-speed? My fuel pump relay isnt getting voltage from the PCM side and I'm out of ideas at this point.
So if you have a PCM you want to get rid of let me know.

or you could just make your own fuel pump turn on ckt. is it ground or positive voltage comeing out of the pcm? eitherway, it controls the fuel pump relay. you could just either put a fused switch power there, so the FP turns on when the keys on, or use a fused switched power source to turn a relay on that will connect that wire to ground. easy, and very cheap eitherway. just an idea. esp. if you got a custom tune in your pcm.

97SS - Keep me posted I may want your PCM anyway to have a spare even if I resolve the issue.
Or if anyone's got an engine bay harness 96-97...i8'll definitely take it since mine is kind of jacked. i know its not particularly my problem but i've been meaning to grab one.
