I spent a year trying to fix my old truck with random YouTube videos
My plan was to save money by doing all the work myself, but after a year and about $500 in parts, it still wouldn't start reliably. The moment I realized my mistake was when a mechanic friend, after looking under the hood for five minutes, pointed out I'd been chasing symptoms instead of the root cause. I had replaced the battery, starter, and alternator, but the real issue was a simple, corroded ground wire. Has anyone else wasted time on a project because they didn't diagnose it properly first?
