https://stream.echo6.co/videos/watch/4f67110e-3768-4077-8904-99b502ea76a4 In this video I take a look at a 1999 Chevy Suburban that cranks but won’t start. The owner has been chasing this issue for a while and even brought it to a veteran GM mechanic with 40 years of experience. After much frustration, the mechanic threw in the towel—convinced it had to be some complicated computer problem. The truth? He actually told me the answer over the phone but overlooked it because the part was “new.” That’s a trap every mechanic can fall into. This video is a reminder to trust the data and follow the diagnostic process instead of assumptions. If you want to sharpen your troubleshooting skills, avoid wasted time, and learn how to solve no-start issues the right way, this one’s for you.
