    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
