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.

I thought about that too and you're probably right that its my best bet because i do have a custom tune. Its positive that comes from the PCM as well. I might give that a try. I'm just hoping that nothing else is wrong with the connecter at the PCM or the PCM itself where the car wont run. I can get the pump running if I jump 12v from the hot lead on the relay to the relay control wire coming from the PCM and the fuel pump prime connecter in the engine bay but I have yet to get the car to turn over and run.

97SS - Keep me posted I may want your PCM anyway to have a spare even if I resolve the issue.
