03 Deville new battery no power anywhere at all car is dead to the key turn need help its in good shape hate to lose it but not trying to spend crazy money can't pull code car is completely dead help please
My 94 Cadillac Deville has been sitting in the shop. Got a call that the pcm was bad. It wouldn't stay running, crazy sounds, just etc. So I got that replaced and ran perfect. Now I'm haven transmission problems. I "suppose" it shifts hard going into second gear and from there it drives perfect. Could it be the Pcm and that they didn't program it right cause I never had this problem until I had one exchanged
my 2002 Cadillac deville act like the transmission is going out and needing replaying.
It stalled on me one day, then next it worked fine. Took the aircleaner box and filter out, tapped on the pcm and it sarted to shoot all kinds of error messages to my dash. Still trying to fix it.
mine runs god when cold bad when warm pcm sendind 2 volts to pcm instead of 5 volts
No drive but . but shift in all other gears how do I fix it
I was having the same issue with my pcm and I send it to be reprogrammed thru an online store
