No prior history of trouble, no customer complaints of misfiring or intermittent no start conditions. The ignition coil failed, of no fault of our own, while servicing the A/C system. What do you do in this situation? Eat it (free diag and ignition coil for the customer), Stop, call the customer, explain what happened and the sell the job (sell testing time and then the repair), Eat the labor for the testing time (diagnostic) and labor for the coil r&r and just sell the ignition coil at cost?, Related videos: No Spark Diagnostics "Control Testing" Part 1 [a free ScannerDanner Premium video] https://youtu.be/7nHbctRwyys No Spark Diagnostics "Control Testing" Part 2 [a free ScannerDanner Premium video] https://youtu.be/9U942uGTZf0 Subaru no spark diagnosis-control testing lecture (a free SD Premium video) https://youtu.be/LdnnFD6J8Uo 00:15 - engine dies and does not restart 00:40 - fuel pressure test 01:10 - initial spark test 02:10 - control testing of the ignition coil with a test light 03:45 - SD Premium plug (SIGN UP!) 05:00 - who pays for this? 09:17 - ASD relay operation (clue that we had a good RPM signal) 10:00 - installing the new ignition coil ScannerDanner Tools: https://www.scannerdanner.com/tools.html https://www.amazon.com/shop/scannerdanner For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.
