Hi all. My 95 f150. 5.0 140k miles is stalling after starting and on the road. Initially I Found no spark,replaced bad tfi module on fender. Thanks Paul for teaching us that diagnostic procedure.
Truck May start intermittently just at the moment the ignition cylinder is released. The butterfly part is broken and will chime when moved, but I don't see how that affects the actual switch causing stalling. So I'm hoping I can get a complete ignition switch wiring diagram so I can backprobe it and see if and where I'm simply losing power, or can I do that at the pcm relay. I don't believe I'm losing power at stalling cause dash lights are still on, am I correct? That's why I'm leading toward a bad cmp sensor or loose rotary vane, or stripped distributor shaft gears. Any insight will help. Thanks
Sorry. Me again, Btw, I'm Peter. I originally thought com sensor cause I would get a coil sparking with Koeoff? How is that possible?,,unless the coil is being grounded somehow ?
