I checked some fuses. Ign fuses and crank. Don't really know what all fuses to check but I'm fixing to go back out and see if I can find anymore that might be the culprit.
So did you have the same problem that I did with no fire at the starter fuse relay?I started a motor without the transmission in before the purple wire will engage the starter if you jump 12 volts to it with a decent size jumper wire
Okay... This is a PERFECT Video for Diagnostic Purposes. I downloaded your video from Youtube and used VLC (Videolan) to Play the Video forwards at Time Slices of 1 Second of Time per 5 Second Slow Delay. I noticed even before you Jumped the Terminals on the Starter Motor that the Small Starter Gear and The Bendix Unit inside were almost completely OUT... and possibly wedged in between the the two sets of Teeth... perhaps due to a Bendix Failure. Also... Just as you did... I observed the Flex-Plate making a Very Slight Wobble at its ecliptic edge. Further, I noticed that the Starter Gear and Flex-Plate Ring Gear where throwing out High Speed Contact Sparks... and Last but not Least... I could hear an asymmetric ringing of the Flex-Plate immediately after Shutdown.
However when that happened... The Starter Gear had either withdrawn inside of its cover dome....or it was being hidden from the Field of View of the Digital Camera focal plane because the Flex-Plate had stopped at a point where it was bent towards the transmission and obscuring the teeth of the Starter Gear. I took some Sequential "Time Lapse" Images as Screen Prints so you can view these at the right pace to visualize and understand the important 'Artefacts of Change' and draw your own conclusions.
My money is STILL on a problem with the Flex-Plate... even if its cause and origin is The Starter Motor having a "Lazy Bendix" as the "Start" of the problem. I would definitely consider changing out BOTH. But there are better minds available here than mine... so lets see what everyone else thinks before you tear into anything. I'd just to say that I admire you BOTH for having the patience to persevere against something that really is ...Quite Maddening. If ever anyone needed proof as to why these Videos are indispensable in such cases to better understand what is really happening ... All I can say is "Wow..." (Or Dare I Say, "Holy Tornado!") ;>):

I wonder why the engine would not stay running? Is the the theft light coming on? I had the same issue where the starter sounded like it was eating the teeth, keep in mind that the flexplate will be a lot more unstable without the torque converter bolted to it also if you unbolt the gear selector switch from the transmission you can plug it into the harness and the truck should start then. I been following your progress just been working alot.
I was examining the pictures of the torque converter bolt holes earlier and I noticed that one of them is either worn a lil or has some residual loctite left behind. Here are the pictures of the bolt holes and the bolts.View attachment 79259View attachment 79260
I just placed my iPhone on a sliding platform and left it underneath the vehicle to record while I jumped the terminals at the fuse box. That isn't a bad idea though!If you can... Get your hands on one of these Nifty Items as it is a Helluva lot easier to use this device that fiddling around the Fuse Box when you really want to be watching from a safe position down there:

That looks like the loctite get it out the hole and burn it if it melts it's loctite.The middle picture on the images of the torque converter is the one that is in question as far as whether it is worn or just loctite left in the hole.
