2004 F250 SuperDuty 6.0 PSD - 220.000 km

Engine died instantly whilst towing - no warning, no CEL.


FICM power - 48.0 volt KOEO
ICP -LESS than 80 PSI whilst crankin - .25volt / 14.5PSI KOEO
IPR - 14.4 PSI KOEO ......84.5% (Duty Cycle) whilst cranking.
FICM Sync - Key OFF = 0 / Key ON = 1

Scanned for codes and got : P2290 & P2291
Base Oil pressure - whilst trying to re-start the engine, the oil pressure meter in the dash cluster moved to "Normal",
so I reckon the LPOP are working.
FICM power didn't drop from 48 volt whilst cranking, I have FICM power and FICM Sync.
Since there where massive drop in ICP pressure (ICP sensor seems OK) I removed the ICP sensor wire just to have the ICU to "pre-set" the value. ICP went up to 700PSI - still dead.

Hope you guys can help out with this one.

Need more information. Do you have gauges that read live data? Like scan gauge II or one of the smartphone apps like dashboss for IOS devices or torque pro for android? They are absolutely necessary in diagnosing problems with these trucks. Scan gauge II can be had at autozone for around 160 bucks. Any number of issues can prevent your truck from starting. Have you tried unplugging the ICP sensor and try starting it?

 

no-start sticky in the Tech Folder might be a good place to start ....

MY bad - my grandson pushed the send button before I had finished typing, leaving me with only a cry out for help with no information....

Thank you guys for chimming in, I'm in desperate need for assistance.

Grate reading - Im saving that tread as a one to have with me in the car.

Based upon your information - could my problem be related to the HPOP in terms of the STC fitting gone bad or a missing check ball causing the pump to leak?
Would a stand pipe or Injector O-ring leak cause the ICP dropping to 80 PSI?

Thank you for helping me out,
Helge

 

04's don't have the problematic STC fitting.

Can you tell us if the ICP sensor is on the passenger valve cover or not?

 

If you've unplugged the icp and it still won't start, it appears you have a hop pressure problem. The 700 psi you're seeing with the icp unplugged is a default computer control value and not the actual pressure. With the icp unplugged you can't read a pressure.

2004 doesn't have the high failure rate ad the 2005 and later. You do have stand pipes and dummy plugs, but they are not the same design as the 2005 and up that always fail. You also don't have the stc fitting that the 2005 and up have that always fail. In the 2004 model, low up oil is normally the hpop. An air test will point you in the right direction.

Bad injector orings are usually not bad enough to cause a significant loss in hp oil unless it's draining into a piston. If so this is a potentially bigger problem with a hydrolocked motor.

 

Late 04's can have the same dummy plugs and standipes as 05's.

btw - I know of one truck w/ 375k miles and the original STC fitting. It was a surprise to me, but apparently they don't ALWAYS fail.

 

Yes Sir - it was.
As far as I remember from when I had the ICP Wire disconnected - it was located at the very front end of the cover.
Then it should be a late 2004 based upon ICP location..or?

If O4's don't have bad STC fittings - could this be a faulty dummyplug, coupler or standpipe leak?

IPR with its screen problems - causing it to zeize up dumping most of the pressure back to the engine, would an issue like this read nearly no ICP pressure but still have 14.5 psi KOEO & still demanding 85% duty cycle on the computer?

Would a O-ring leak normally cause a leak this big?

Thank you,
Helge

 

You should do the air pressure test

 

Thank you guys -if some of the 2004 can have the STC and dummy failure makes me think that this is related to a huge oil leak.
Good to hear that O-rings normally don't give huge leaks like the one that seems to present in my case.
I need you guys to put me in the right direction and starting point BEFORE loading the BuckZooka.
I'm totally on my own due to non existing dealership and hardly no workshops around that do US truck's - so your know-how are gold to me.

At this stage I'm leaning towards a HPOP/IPR leak or failure and will probably check the pump out before anything else.

Just for comparison - your 60K$ 6.7 King Ranch are 250.000.K US$ at my place - with parts more than double $ due to fright and greedy vendors.

Thank you for time and will to help me out,
Helge :-)

 

Yes - I need to do that test. I'll try to organise an air hose fitting that go into the rail on monday.
Thank you for the advise,
Helge

 

Mark, this is the first I've heard of the late 2004 having the same stand pipes and dummy plugs as the 2005 up. I've got to check my documents to prove it to myself.

 

see post #6

 

maybe start w/ when the wavy oil rails were introduced (2004 btw) ........................

or look up what year models are serviced by the standpipe and dummy plug kit - part number 6E7Z-9A332-B
