7.3 Turbo IDI won't start.

94 7.3 turbo shut off while driving, lost battery voltage as well. Now it won't jump start, it will not even crank. Any ideas what could be wrong?

What do you mean by 'it will not crank'? It will not turn over or it will not fire? From what I am reading your truck is dead electrically. Do the head lights work? If not then start checking cables for tightness and make sure they are clean; grounds also.

I can get lights if I hook another vehicle to it. I then turn the key to crank it and lose all power and the truck will not crank. I was thinking maybe a battery cell dried up or something. Batteries are just 150 bucks each so I wanted to make sure before I did it.

You can take the batteries out & have them tested at the place you may buy new batteries. Replace both even if only 1 is bad.

Test the batteries, but shutting off while driving seems to indicate your batteries were not being charged. It takes a LOT of amps to crank one the these engines, which require a strong vehicle to jump off and LARGE jumper cables if your batteries have completely gone dead.
