No number on scanner, the inspection is up at the end of this month. How long will it take for the relearning process to be over ?

I have replace the ecm a year or so ago unfortunately I do not have the paper work with it anymore, Does this sound like the ECM is bad again? The one I replaced it with was a remanufactured unit, thanks for any input!!!

Relays and grounds . My 96 has taken me to hell and back with these relays and grounds. My 93 did the same thing and I sold it to a more ambitious fellow.keot blowing pcm fuse due to a bad ground rubbing through and making contact with a hot.i am more ambitious now,don't wanna give up my 96 so I am running a rat race in a hamster cage chasing all the wiring problems and it's so many I can't even count backwards that far,but seems I have had both the problems you have had and it was insufficient dirty grounds and relays get glazed,but be careful cleaning. So you don't push connectors down to far in distribution panel.window relays crap out on everything,and engine light you will have. To diagnose and come up with h a code fun,fun,fun.
