GM Troubleshooting Part 1 - Ignition/Fuel Injection/Timing/No Start troubleshooting - Introduction

This is part 1 of a multi part video series about how to troubleshoot any ignition, fuel injection or timing issue with some 4WD and starter diagnosis thrown in at the end. I describe the vehicle as a 1994 GMC Sonoma 4.3L Vortec V6 CPI vin "W" that was running rich (dtc 45 - O2 sensor rich) and then would not start. This video series contains a lot of the information I learned during the troubleshooting process. In the end I believe it was a dirty distributor position sensor connector that cleaned its terminals when I unplugged and replugged it to the Ignition Control module.
