2002 Chevy Cavalier No Start (a direction based approach)

In this video I will show you how to use simple, fast testing methods to determine diagnostic direction with a no start condition. All tests shown can be applied to any vehicle, aside from the GM Type 2 ignition coil test. While Snap-On diagnostic tools were used in the video, any basic code scanner and multimeter could be used with the same results.
