I don't know but when the computer is hooked up it doesn't show any codes. I've had this vehicle a long time and I've never been able to get codes read.

Alright you have what's called a hybrid connector obd 1.5 the 16 pin wasn't fully in effect till 1996.so the pre 1996 gm cars and trucks with a 16 pin connector most of the basic scan tools I know of wont read those cars and trucks codes.You need to find a shop with a tech1 tech2 or more advanced scan tool that can read the codes with the hybrid connectors.Lets start there with the codes that will lead us in the right direction.Let me know the exact code numbers and not code descriptions.This might be a tough one since you have the hybrid connector and the scan tools wouldn't be cheap to buy a scan tool to help you repair it.
