2003 F250 6.0 Died, no-start

F250 6.0 2003, Truck has 236,000 miles. Noticed loss of power topping a hill at 70 mph or so, next smaller hill, wouldn't make it up hill, but would still idle, but not rev up past idle, then died, no start. Buddy pulled me home, starts next morning when cold, only revs to 1000 or so, idles a bit, then dies, then no start. No start now, but seems to want to, with some cranking it gets to a sort of higher than usual cranking speed no start, sounds like a cylinder or two are hitting, but still no start.

Oil looks good, it was changed 2,000 miles ago.

Replaced fuel filters (I was a little past due, but not much).

Replaced air filter.

All injectors were replaced at 200,000. miles.

Checked fuel flow to top filter - good flow, no air or water visible in fuel.

Suspected pump, but pump running sounds normal.
Checked fuel pressure at top test port and got 48 psi.

It's not setting a check engine light, I don't have a scanner to look for codes.

I appreciate the great no-start writeup sticky, but was wondering if, based on description of problem, someone here might have some advice on what would be good to check next?

I don't have any diesel repair experience, but do have lots of other maintenance experience.

I don't have a scanner (as mentioned) or any special tools for this truck. Do Have a Fluke 77 and am proficient with it.

Any suggestions? Should I send it on to the shop? Buy a scanner? (Anyone rent those? (Questionable whether I can afford to send to shop, but I also can't really afford to be without the truck for any extended period either, too much work to do to stay afloat!).

Thanks for any help.

Tex

PS: On edit, my problem sounds a lot like Droopies' Excursion!

Sounds like a leak somewhere in the High Pressure Oil System.

It does sound like the HPOP system has failed, when mine failed it would run but not start or idle(had to ether it to start it).

Since yours slowly died and now wont run at all It sounds like yours failed differently.

You can test the low pressure oil system by taking the oil cap and filter off, having somebody crank and see if the bowl fills up(dont crank for long!). I'm sure there is a way to test the high-pressure system as well, but I cant recall how.

Good luck!

sense the injectors are fairly new i would assume that the o-rings would still be in good shape. the oil filter housing doesn't always fill with oil while cranking with the cap off due to the filter drain valve at the bottom thats opened when the pressure is released from the filter. If it were me i would get it on a good scanner ford, mac or auto enginuity and monitor the pressures on the high pressure oil system while cranking. if you don't have any access to a scanner there are a couple things you can try without it although on the 03 with the icp sensor on the hpop its not easy.. first pull the plug on the icp and see if there is any oil in the plug itself the icp on the 03 is bad about failing do to its location and the heat that builds up back there. if the icp looks to be OK pull the IPR and look at the screen on the end of the valve if the screen has a hole in the middle of it you probably got some trash in it you maybe able to take the IPR apart and clean it i know you can on the 7.3 but have never tried it on a 6.0. if the IPR looks ok then i would then lean towards the SCT fitting thats beside the hpop under the cover or the hpop itself.

I hope this is of some help wish i could do more but Dallas is 6hrs me and I'm not planning a trip up that way anytime soon that i know of

one more thing pull the radiator cap off the degas bottle and make sure you don't have any oil in there if your oil cooler failed it can allow coolant into the hpop and also cause a no start situation

Thanks y'all for the help. I forgot to mention, had ICP replaced 6 mos. ago.
I'm liking the idea about getting a scanner on it. In the past I was able to limp over to a buddies' but he's a full time pro, and I don't want to borrow his equipment.

Is there a way to get a reasonably priced scanner that'll do anything I'd need on this 2003? Like, can I shop for an older Mac and get a good deal on it, or does that kind of deal exist? Maybe they just keep udating the software and keys, so you don't see these for sale as older units?

I tried looking for oil pressure on the gage while cranking for a good bit, gage doesn't move up at all / showing no engine oil pressure.

I gotta say, I love this truck, bought it new and put all 236,000 miles on it myself, about the only real repair its needed was the injectors at 200,000. Lots of those miles pulling 14k gooseneck at max., so she doesn't really owe me anything.

I am having the same exact issue with my 03... My local performance diesel shop said to test the FICM however i havent had time to touch the truck because i am in the Navy and out to sea A LOT! Anyone think that it might be the FICM or should i skip that and look into just replacing the HPOP and associated seals and such? Any help would be greatly appreciated!
