Hydro And still are reluctant to do the air test -- such a simple thing todo, and yet yields a lot of information

The IPR fitting is about $12 bucks -- add a short hose and valve(just because that is handy) and still less than $25

Throwing parts at a problem without testing is never an economical solution -- either in time or money

jmtw You mean the STC fitting? I checked it when I put the IPR in and it looked good. Wasn't blown off, anyway. The IPR improved the oil pressure to 3something, but not the 500 to start it.

bismic I didn't say the HPOP was bad. That year model has a weak HPOP discharge fitting (the 05 and up HPOP is actually quite reliable itself). If that fitting is still original (and it may be a big if - who knows), it is either bad or soon to go bad.

jmtw I'm going to do the stand pipes and dummy plugs since they're inexpensive. Or at least pull a valve cover and see if they've already been changed. Never can tell on used trucks whats been done and what hasn't.
As for the HPOP, I'm probably wrong, but I just can't see it going bad from sitting 3 weeks because it's mechanical. It ran a steady 1800+ pressure whenever I checked it.

bismic An air test on a 6.0L is a common thing to do. Fixing the STC fitting and the dummy plugs and standpipes are a necessity. They are relatively easy to do and every 2005 and up (and late 04's for the dummy plugs and standpipes) need these upgrades for reliability.

At 235k miles, it should not be a big surprise for a transfer case motor to fail. Maybe even time for a new HPOP. That is about when my 7.3L needed a new HPOP, new fuel pump, and its second new transmission.

If these things are a problem for you to take on, then I agree - time to part ways with it.

jmtw I meant IPR, not ICP (I had already changed that a few months ago).
You're right... they're not unique and certainly not unsolvable. There isn't anything that can't be fixed.
But. At some point you have to draw the line and say enough.
Being a swb ext cab that was used as a work truck, it just doesn't have the value (at least not here) to make putting too much time and money into it worth it.
The F350 is a helluva lot nicer, everything works, and it's a crewcab lwb. Plus, it's gets better mileage.

Not enough to start it, obviously.
It was fine last time I ran it, close to a month ago.
Can they go bad sitting? I wouldn't think so, but something screwed up somewhere.
I'm assuming it's mechanical and messing with the ficm shouldn't have any effect on it.
And yes, it's full of oil

Thoughts? I'm at the point I'm seriously considering selling what parts I can and scrapping the rest.
IMO you need to do an air test. Probably you are going to need new dummy plugs, standpipes, and an updated STC fitting. You may also need a new IPR valve.

Your problems are not unique and certainly aren't "unsolvable".

jmtw Thank you all for your help.

jmtw I gave up on it. I tried a new ICP, just to be sure that wasn't the problem with it not building enough oil pressure to start. Went up about a 100psi, but didn't reach 500.
I got a 2000 F350 cc 4x4 with the 7.3. It's been built and studded for a decent price, so I'm sticking with it.
If anyone in the MS area needs a parts truck or parts, let me know.
I did put the bumper, grill, header panel, and headlights off the '05 onto the 2000. I have everything else, though.

bigjimnv Just wondering what ever became of this. I'm pretty new here but, I can't imagine the engine could run without FICM sync. Did you key the PIDs for these into TorquePro yourself? I wonder if you get a bit wrong.
FSYNC its 2209cd with an equation of {A:1} and ODB header of 7E0
sync is just about the same, but eq of {A:0}

i.e. these are single bit values.
