997 gmc suburban. fully charged battery. Turn key to start, nothing.No click no starter noise, nothing at all.Accessory bypass switch is working. All cables are tight. Do I have an ignition switch problem, relay/starter problem? This is an intermittent problem, and gmc dealer has not been able to diagnose because after the vehicle sits over nite, or really cools off,it will start. My gut tells me it is heat related. What's up?
Did they check the Igintion module?
check the crank fuse on the side of your door ?
