    Removed the tranny to replace the dampener plate. Reinstalled the tranny and now it won't start. The traction battery was replaced, now I am getting a p0a0f with a p3193, but I have fuel pressure and a full tank of fuel, but the fuel gage is showing empty, 1 bar flashing. I replaced a ground strap that was rotted off. It ran fine before I took it apart. Now it just bumps and doesn't roll the engine over at all.

    I don't ever remember any bumping usually when that thing starts to turn over the mass it rolls around a few times then stops . Like a real smooth big heavy starter with no lag it just cuts in .

    Can you post a video? Maybe try to have the camera showing the crank pulley in front as the sound picks up the bump?
