YJ computer question
Does anyone know if the ´95 YJ PCM waits for a signal from any sensor before providing ground for turning on the check engine light, ASD relay and fuel pump relay? Thanks |

Heh, no idea but if you don't live in the high desert like I do all the
ground connections are rusted by now... Cheers, Earle "nrs" <neale_rs@yahoo.com> wrote in message news:1191249224.014494.138940@w3g2000hsg.googlegro ups.com...

This problem has been going on for a while now and is mostly documented in the "Delayed start problem" thread. I've tried a lot of things including cleaning the ground connections and just can't figure it out. I'm considering taking it to the dealership at this point, regardless of the potential cost. |

That will isolate whether the problem is interior to the PCM or not, and may be cheaper than a couple of ASE mechanics scratching their heads for two hours on your dollar. My '95 YJ has always taken one or two seconds of cranking before it will fire cold. It did this new, and I always figured it was part of the nature of the beast. Has it thrown any codes? They say you can read them by switching the key on and off a few times and watching the check engine light flash. Cheers, Earle |
