Truck was running fine one day and the next it wouldnt start. Lost fire. Check igntion module, Nothing. Check all fuses none blown. Have no blinkers either, But I still have all other lights and flashers. Dont know what to check now or where to start. No fire at the coil

Key on check Pink wire that is same wire powered by ECM1 fuse as injectors. So if no voltage then something a miss in wiring. Here is a guide and the wiring diagrams so you can how how the system works.
