Anyway, your advice makes logical sense so I'll try that again and
hopefully, I'll have more luck.

Thanks again for your help.

------------------------

The procedure we used was like this:

One guy cranked the engine while the other slightly loosened the fuel line
nut until fuel started squirting out. You could see the air bubbling out
as well. While still cranking the engine, we'd re-tightened the nut,
then we'd move on to the next cylinder. Like I said, it took several
times on each line to get all the air out so the engine would stay
running. In fact, we killed the battery and had to take a break while
recharging it halfway through the process.

There may be an easier way, but neither of us were diesel experts. It
worked though.

Another suggestion ....

When it starts acting like it's trying to run but still dies, open the
throttle up quite a bit before you start cranking it. Like almost wide
open. Sometimes the extra RPM it builds up allows it to stumble through
the last remaining bubbles of air.
