Left on hunting trip last Thurs. Blew tire on trailer 6 miles from home. Shut off truck. Went to restart, cranks only. No codes. Towed home.
Thought it might be a fuel filter problem. Had just changed oil/filter and fuel filters prior to trip. Checked filters, upper bowl was low. Turned key to on and bowl filled up. Noticed filter wasn't snapped in lid. Also checked lower filter.
Drove it to work this am.
Turned off truck and tried to restart to check. NO START-Cranks fine!!!
Need advice asap. Please. Thanx in advance.


Temps in 50* last Thurs morning.
60* this am.


Normal operating temps per Scangage

 

what is Scan Gauge reporting for ICP, ICPV, and IPR%?
Anything on fuel pressure.... low bowl could be an air leak on an o-ring for a filter or something in the tank.

 

What year 6.0 is this?
Miles?
Maint history?
Any pertinent info is helpful

 

2006 f350
115k milage
No trouble in 65k miles.
Haven't check icp or rest of the list you left.
I can hear fuel pump click off while waiting on glow plugs.

 

Truck starts easily after it's cooled down?
As Randy mentioned some numbers would be helpful.
During cranking, after start up and warmed up, then again attempting a hot start.
Sounds like a HPO leak initially...........starts up after she has sat for a cool down.
Hot oil won't pressurize as easily....although it's not a given you have a leak on oil side. Might be ICP or IPR.
Will it light if you try to start hot and ICP unplugged?

 

Any work performed previously... like updated STC or dummy plugs or standpipes?

 

No STC /dummy plugs/standpipes to my knowledge. Bought 5.4 yrs ago with 49K
Aircraft Mechanic by trade-Not diesel mechanic but I have been as far as oil cooler in this engine. Feel very capable of doing the work myself.
How do I call up ICP, ICPV and IPR%?
Suspecting HPOP and who to buy from? How to get to it?
Not stranded, my daily driver is a Jeep.
Thanx again!!

 

FYI
Wouldn't start after parking for lunch. 6 mile drive.
Returned after an hour started fine.
Tried starting it after return-It did start but took and extra 10-15 seconds.


Will get numbers tonight. After I figure out how.

 

your HPOP is the good one, rarely has issues. But that year had issues with STC fitting, dummy plugs and standpipes.

I'd do an air test (see tech folder) to isolate the issue, then watch a couple you tube videos to see how to make the repair. Dummy plug in the passenger side is usually an issue as is the failed STC fitting. Diesel Tech Ron on you tube has some great videos on air test and these repairs... walks you through the whole thing.

Post up the ICP and IPR readings. Go to the Scan Gauge web site and read how to program X-Gauges for 6.0, or again, watch Ron on you tube, he goes thru that as well.

Cold oil is easier to make pressure, once warmed up, leaks become gushers and why is starts when cold but not hot.

 

Finally an update. Loaded ICP IPR and SYC into scangage.
Readings as follows: First start of day.
CODE ____Cranking_______ Idle________ Warmed up _________After 12 mile________ Cranking No start
IPC _______ 473_________ 873 __________ 1051 ______________ 586 _________________288
IPR_______ 14.8 _________27.7 ___________32.4 ______________22.2 _________________84.7
SYC________ 0___________ 1 _______________1________________ 1___________________ 1

Have dummy plugs and stand pipes in hand( as in new ones)
Did not locate a code for ICPV

 

Cranking no start tells us engine is looking for full on oil and only getting just more than half of what it needs to light up. You need an air test as Randy says, but odds are a HPO leak.

 

If your going to go for it, do the STC fitting as well, I'd do an air test to be sure or you could be doing extra work. Those three things are a good bet one of them is the issue.

 

Going in after Dummy plugs and Standpipes fri night. Have STC fitting and HPOP "O" rings and gasket on the way. Since that's basically 2 different areas to work on, I'll do the DP-SP first- If that solves it, I'll have the STC fitting in hand an a month or so later, pull the turbo and dive into the "Valley of the Oil". Probably should order updated turbo drain line too.
Let me know if I should change anything else in the Valley.
Things are gonna get a little dirty Friday night.
FYI did see 3400 IPC while road trip testing with throttle almost to the floor.

 

Was that 3400 cold or at 190°?

 

186 EOT Was headed home from warm up trip.
It was 90*F here yesterday. Didn't take long.
