I had a driver sit beside the road for several hours on Friday because the ECM wire came loose from the battery and shut the truck down. It was just a sudden engine light flashing and it shut him down. This sounds like a similar scenario.

Either got a reading on the tach but still not reading anything on cat et and no power to injectors. Tested injector circuit and the timing circuit and all passed. I have a service manual here that says on pin c on the cam sensor with key on should be less than 2v or more than 10. That passes. While cranking you should have 2-9v. I have 11. Screwing the sensor in and out made a slight difference in voltage but not quite getting me into the desired range. Tried this on the new cam sensor and the old one with the same results

Check your 12v pin for ignition on to ecm? Those go bad...
Though with ecm power im assuming thats good -
