A free ScannerDanner Premium video. This is a raw (unedited) video taken from my Engine Performance class this morning. I used this opportunity to review ignition systems with my class as well as to try to help one of my YouTube subscribers. His question was on a 1991 Mazda 626 with a no spark, no start problem. The information covered in this video goes above and beyond this Mazda system. I will be teaching you fundamentals that will help you troubleshoot a no spark problem on any car!
