*updated* Sudden shutdown (again) - Truck will not re-start
Had one weird episode two years ago (almost exactly to the day): http://www.steelsoldiers.com/showthread.php?77049-Sudden-shutdown-cause
The same thing happened again. This time en route to home, with a 4 1/2 ton load of gravel.
Driving normally, about 45 mph. No feeling of power loss, no excessive smoke or strange engine noises. I went up over an overpass and on the downhill the engine simply shut off, as if someone had pulled the shutoff lever.
I coasted to a stop at the side of the road. My tank is, again 1/4 full, so initially I thought "darn, ran out of fuel". I have not worked on or tampered with any component of the fuel or injection system in a long time. Truck has been running flawlessly for two years.
Last weekend (!!) I installed the tow bar brackets in the bed and carried the tow bar for the first outing. A friend towed me, gravel and all, with his Toyota Tundra (!) in 4WD low about a kilometre to his yard where the truck sits now, safe and off the road. Don't ask how we rigged the tow bar to his ball hitch; we got there, slowly and safely.
Here is the result of the primary examination of the patient:
I stopped at NAPA and, following the principle of simple things first, picked up a new primary and secondary spin-on fuel filter.
Where do I go from here? I have never tampered with the HH and am reluctant to start. Advice welcomed!
I am planning to follow the advice in this thread: http://www.steelsoldiers.com/showthread.php?69241-Removing-rebuilding-reinstalling-Hydraulic-Head

Here is the result of the primary examination of the patient:
- fuel in tank
- in-tank pump runs
- cracking the bleeder on the spin-on primary fuel filter drenched my shirt in diesel spraying out under pressure (in-tank pump works).
- With the in-tank pump off, the fuel merely runs out slowly.
- cracked injector lines at the injectors with shop towel around the fitting; cranked engine: no fuel at injectors
- shutoff appears to operate normally; the collar slides backwards when pulling the shutoff and forward when released; it appears to sit against something when it is forward; appears normal?
- took batteries out and put them on a charger; they were getting weak.
- Unrelated, when pulling the snorkel off the air intake there was a "nest" of torn up shop towels and hair. Looked like a mouse or chipmunk nest. I have no idea how they can get in there. The air filter is on one side and the "snorkel" with the wire mesh on the other side. I had everything off two weeks ago when I installed the hood lift and it was clean then. Weird. Cleaned it out but that still does not give me fuel at the injectors.
