Hi all,

       f-250, 1991 pre powerstroke 7.3 4x4 stick.

       Upon first starting the glowplugs do their thing, I crank, it starts,
runs(no more than a few seconds), and quits like it ran out of fuel.
Extended period of fast cranking later it fires up like nothing was wrong.
Then it will run all day with no further problems. Next morning, same
problem.

       A little history. Batteries are about 5 months old. I have gone
through the glow plugs recently. Immediately prior to this new problem some
of the plastic fittings on the fuel return rail cracked. I replaced the
fittings. Bled the air out of the fuel filter. I find no leaks on the motor
fuel lines. Now this new problem, I'm stumped.

Any takers?

Thanks in advance for any replies.
