Ran out of fuel, over revved with ether, primed but now will not run, even on ether?

The truck had run out of fuel on the highway. Tried to prime by forcing fuel into fuel separator at fuel tank. (Couldn't open cab)
Tried to start with aid of ether, over revved while cranking with accelerator floored and spraying ether. Ran extremely high RPMs for a second or two.
Then it would chug between 700 and 1,500 RPMs randomly, with accelerator floored only. Very much black smoke while chugging.
Batteries down. AAA came to jump but their jump pack was drained. AAA driver tried to "Tighten terminal" with a hammer.
The second AAA driver found a broken terminal and tried to jump. Also with a drained battery pack, no start.
Next day, (still on side of highway) I brought New NAPA Commercial Batts. Primed by the book. 1) pump through fuel line into the fuel filter, 2) pump till no bubbles out of line out of filter, 3) pump till no bubbles out of filter housing vent screw. 4) pump the primer sixty times. 5) engage ignition switch, depress idle down switch and pump sixty times.
Tried to start, cranks, no start. Shot a quick blast of ether into filter housing with filters removed, no start. Acting like it fired maybe three times.
Repeated above process. Again, no start. This time I shot two one-half second blasts of ether directly into the intake manifold (removed rubber hose at intake). No start.
Repeated entire process with a Helper holding the idle down switch while pumping primed sixty times, still no start.
I'm running out of time before the State Troopers impound it.
Don't want to tow to dealer if it's a damaged engine and pay them the $600.00 diagnostic fee to hear it's exploded. (It sounds and cranks fine)
thinking a sensor from over revving or hoping anyway.

Addition to above post. The idle up/down switch has not appeared to work for some time now. So, I'm guessing the idle down switch to bleed the injectors may not have done anything.
