99 Honda Civic No Spark Diagnosis with a Test Light

I will show you how to troubleshoot the entire ignition system, including cam and crank signals, ECU to igniter control and igniter to ignition coil control using a simple test light. A follow up test will be done with a small single channel lab scope, showing yet another way to verify the same condition.
