Check the IDM relay on the firewall for burnt terminals. Also check the 3 infamous fuses in the battery box.

What year is it? Ford pretty well took care of the STC (Snap-To-Connect) fitting by '05-'06.

If you have access to an IDS it will help you. It's possible the sensor is bad. The STC fitting is on the back under an aluminum cover. I have seen them blow hard enough to bust that cover. In a truck, if I remember correctly, you have to pull the tranny to get to it. I take it this is in a bus, hopefully with a doghouse?

There are other things to check 1st before going after that fitting.
Someone recently posted a great well written procedure here, cant remember if it was under a 6.0 or 365.
Other possibilities, faulty IPR, pull it out and check the screen, sometimes it is cracked or missing, debris gets in and holds it open and relieves the pressure.
Not saying it isn't possible, but I have not seen the fitting fail for several years now, but have had several IPRs go bad.
If the screen is broke, get a new one. If it still doesnt build pressure and start, you now have a good test IPR :)

Sounds a lot like an ipr issue to me I would easily go that route first atleast in my experience with the 365s its more common of a failure and easy as well . Could be wrong but that's my first hunch Id go for .

The IPR, that's what I was going after when I said "sensor". Getting old and can't remember things like I used to. It's been 5-6 years since I messed with one.

Seems like there's also a screen in the valley for the HPOP that can get debris in it and restrict oil flow, but that's a "deep" repair, too. As torgue posted, most of the bad STC fittings have probably been dealt with by now and the later engines didn't have that issue.

well i put air in the system and i heard a big leak in the pump area so i took the pump cover plate off and pump air again and there was big air leak but i could not tell where it was coming from so i used my smoke machin and found it was coming from the small holl behind the gear would that be a pressure relief valve do i need a new pump

Not yet! You must energize the IPR (to close the system) while testing for internal leaks in the high pressure oil system. If you dont energize the IPR, you will here a leak behind the gear. Dont overlook the oil tube and plug D-rings in the oil rails too.

Dsalinas could be wrong but anytime these 365 die on the road would shoot the ipr first **they usually always fail hot and cause low icp issue , everytime in my experience ive had high press oil leaks on these they **will stay running ** just don't want to start hot but once started usually stay running at least in all the times I have seen, unless of course a major external leak like fitting blows off and oil is all over . Just saw on the first post where you said it died on the road didn't read that before . Could be wrong but that's all ive seen out of the 365 ive worked on .
