hi everyone. I am working on a 94 ciera with 3.1 . it will start and run great then after driving it 15 min or more it wont start. it will sputter. i had an extra module and coil pack so i put it on and it ran fine for a while. now its bad again. it seems to be a yellow spark when it wont start.
i plan on doing fuel pressure test today. but the HOT/COLD thing puzzles me.. thanks in advance for any help..................87Racer
