02 Grand Prix 3.8L (no spark, no fuel)

Asked by Michael Jun 21, 2016 at 11:22 AM about the 2002 Pontiac Grand Prix GT Coupe

Question type: Maintenance & Repair

I'm working on a 2002 Pontiac Gran Prix 3.8L
I've checked fuses and relays, all check out good,

disappeared at the same time.

What do you think?
