ok i have a 92 i/c well here is the issue i have no charging and no overdrive unless i let the truck run for 30-45 minutes then all of a sudden i have great voltage and over drive i scanned it with my snap on mt 2500 my solus will not comm. but i watched it from cold to hot which took forever and when its cool i cant get anything then my cts reads from2064 degree back to about 50 back and forth then works normal also i get no rpm readings then perfect i am going to blow this thing up soon

also while this constant crap happens my wait to start and check engine lights flicker dimmly until BAM perfection cant get a code cant get much info on alldata and im not strictly a diesel mechanic i need a new direction throw me a friggin bone here

sounds like you may have a bad ground at the pcm. Check them, maybe even open up the harness and look for any corrosion. Could even be the pcm itself. Find a wiring diagram of the pcm, test for your power in and ground feeds, if they are good, then something in the pcm probably shorted.

i have had everything out opened and taken apart i have performed every test known for this damn thing i even pulled the pcm out and took it apart looking for corrosion or burnt channles i am at a loss i even took a vantage pro which has one of the fastest capture rates and could not find a glitch anywere that is what i am saying im lost and i dont think its the pcm it is to exact to be the pcm it has to be something altered by heat oh and i checked every ground i could find is there some im missing?

yes and i have tested every wire from point A to point B what really pisses me off is some kid had this truck before me and i am starting to think he may of tried one of these great FREE POWER ADDERS and screwed with the wrong thing dont get me wrong but there is some great advice on here and some really BAD advice like for instence i had to replace the fuel pin due to massive runoff because he ground it down to a nub he told me it was made to match the denny t stage 2 what an a$$

Ok I am going to throw some pin numbers and I need the readings from a meter.

Pin 11 to battery ground terminal. What is the OHM reading??

Pin 12 to battery ground terminal. What is the OHM reading??

Pin 5 to battery ground terminal. What is the OHM reading??

Pin 9 with the key on. Does it have battery voltage??

Pin 3 with the key on. Does it have battery voltage??
