Ok got it up and running... When it comes to something failing for me it is always the " I have never heard of that failing like that before" or the " that shouldn't cause that". For me and everything I work on weather it be cars houses machines you name it. For me it will always be the most obscure failure mode known to man that not even the engineers have even thought about it...
I went over what it was telling me in the code.. Now I have learned to distrust the usual testing and methodology as for me it rarely works... Got to thinking about the neutral to ground and hot to ground. Now the meter said it was good but... I say don't trust it cause I know better...
So I figure let me bond the neutral and ground at the unit and see what happens. Lo and behold all is good again and working perfect as soon as I connected them. So I undo that and go to the panel and move the ground to another hole same with the neutral and get them nice and tight again and then pull the bonding screw and clean it a little and crank that screw back into place.
Now we are all good. The meter was showing it as just fine but for some reason the board is extremely finneky and sensing something my meter couldn't.
Now I can tall you about the 94 Le Sabre I bought as a dealer buyback since they couldn't fix it. Had 20K on it and I paid 3K for it. Check engine light would come on as soon as you started the car for the coolant temp. They tried everything except...
Through my experience with those ecms at the time... I turn the key on let it sit for a few seconds before trying to start it. Crank it and no light and all is good. The ECM was bad and they kept preaching it's never the ECM it's wiring etc. I was letting the ECM warm up.
I put a $100 ECM in it drove for another 140K with minor repairs and would top out at 36mpg on the freeway...
