1992 Buick Riviera Q&A
1992 Buick Riviera Question: Engine has no spark. Why?
you have thrown enough parts at it with no success. you need some help from a shop to track it down. you need to verify power and grounds to the module and the pcm. that is a start. Roy - mastertech6371
I have a 95 Supercharged Rivi and having the exact same problem, did you ever find out the issues? I've replaced the fuel pump and many different sensors etc. Still nothing, it won't start. It use to start then would just die out, now it just won't start. - FGuerrero
