My guess is that the first repair facility misdiagnosed the problem, but
it's only speculation on my part.

My story:

Bought a new, '05 F-350 Powerstroke.  At about 6000 miles the high pressure
oil pump (this is what actuates the injectors)  died on RT 95 near Savanna,
GA.  I was towing a small trailer from Florida back to my home in MA.

Spent 5 days in a hotel (at my expense of course) while an authorized diesel
repair shop tore the engine half apart to replace the pump and pressure
regulator.  There were no Ford dealerships in the area that worked on
diesels.

Got home, and a couple of months later I took a trip to Norfolk, VA.   Just
got started on the return leg and the truck died again.  Local Ford dealer
couldn't even look at it for several days.  Decided to have it towed all the
way from VA to the dealership in MA. (again, at my expense).   The new high
pressure pump had gone bad.  This was at 8000 miles.

At 12000 miles the check engine light came on and the truck started losing
power.
Took it to the dealer ..... bad turbo.   It was replaced.

Since then, it's been fine.  I drove from MA to Denver, CO and back towing a
car trailer to pick up an older, classic pickup truck.  The truck performed
perfect. Now, (knock on wood) it has 26,000 miles on it and it has been
flawless.  Not even a hiccup.

Even the best of engines can sometimes break down.  They're not all
manufactured perfectly.  I have a 2005 F350 diesel (6.0L) with 45,000
miles on it.  I've had two problems; a faulty sensor that falsely reported
"water in fuel" at 30,000 miles, and a disconnected alternator wire that
caused two batteries to go bad at 42,000 miles.
