Videos of the electronic governor with the back cover removed. First video is of the key being turned on. The actuator jumps up to the top and then immediately returns to the bottom. Second video is a starting attempt. The actuator remains at the bottom despite the fact that I am activating the accelerator pedal. I'm assuming that bottom position turns off the fuel as is where it sits with the key off, functioning as a fuel shut off solenoid. I presume once the key is on, it should rise up a little bit to allow fuel to flow to start and idle. I'm not certain of any of this but my initial hypothesis that a fuel shut off solenoid wasn't opening fully (at the time I didn't realize the truck doesn't have a traditional fuel shut off solenoid) seems to be correct. That electronic fuel actuator is not moving when it should be. I presume that could be caused by failures in the electronic governor itself, in a sensor, or even in the ECM or wiring. I did check the connections immediately adjacent to the electronic governor and they were pristine.
