when it comes to electrical sources, these cars can be finicky .. often even "correct" aftermarket units dont work on all the cars and one has to fall back to the dealer's OEM units.

i hope you also cleaned the grounds and gave them a nice coat of dielectric grease to prevent an return of these e-ghosts - you did see that thread in our FAQ section, right?

yep, I've been cleaning and using the dielectric grease and its very helpful. I believe I may have a low voltage in the starter as well as a parasitic load drawing off the battery when the car is not running. what systems in the 93 generation Deville have a draw like this? Possibly the radio but is there anything else?

well, now I'm throwing a few more codes, 12, 13, 41, 52, 91
The car has started shutting off right after I get it jump started and charge it about an hour... then I go to move the car, turn on the lights and it dies on me...
