and from what ive researched is a known issue failure due to corrosion and mechsnical breakdown of the actual splice, when these LH pltform 90s years cars are an unexplained no-start or random stalling ec,. maybe not having alternator connected and starting running it caused overload of power and fried this splice or what was left of it,. is all i can figure,. if it didnt overload fry a circuit inside the ECM, anyways. or overload a ground wire for ECM to body or drivetrain bellhousing bolt etc. in which i dont remembr now if i have ever tested/checked, either, hmm..

tiem to go ujt with test light 12 volt lamp probe and aso the digital multi meter and a knife blade and start peeling back sheathing and tracing and finding splices and test for voltages and grounds etc,. to confirm rule out any last things like this before really going and finding getting another ECM for it. one last time for testing etc so i know that ive done it all for sure definitely, at this point. becuase ive definitely not opened up main drivetrain ECM harness or anything its all stil factory untouched sealed uncut etc,. so...

i ran it withtout the ALTERNATOR. ive ran this car without a battery MANYtimes and its always been fine. it wasnt until i ran it without the alternator that it stalled died right away and hasnt started run since.
im trying to understand how or why runnign without an alternator could hurt anything. it definitely did.. somehow.

anyways, the ASD is energized powered up 5v as are the FP and all the sensors. im at a loss. what else can be going on here besides the PCM? esepcialyl when it was perfectly fine before starting without alternator?
This is wearing it down - why try to run it without an alternator?


so i must say with the trep having no lack of electronic control - back out a step to the configuration that it last started?
