1988 gmc suburban
I ha e a 1988 GMC suburban. I have replaced the battery, alternator, also the starter the truck will not start. All parts were boight at advanced auto parts. Any won't have any answers of why it won't start. Before it would start right up and drive with no issues. Now when I turn the key I get nothing. Am the lights work on the truck so I'm getting power. But I have no idea why it won't start.
