Long story short. 2003 6.0 psd owned two years driven 2 months due to money thrown prior to forums and scangauge 2. Bought truck in chicago drove home. Oil in coolant. Did egr delete oil cooler all gaskets orings etc. New oil filters motorcraft fuel filters .new rad fluod wix trtmnt. Truck started right up. Still had same intermitantstudder as always when cold. Always exp those sysyems until hot then here and there until parked then hot no start or hard long start when hot. Knew something was wrong and waited for it to come to a head well it did in may.
I was driving coming up to a stop sign and truck died like i shut key off. Refired once off ether. Lasted 3 seconds died no restart period didnt even want to just crank crank crank.
ok towed truck i thought it was injector orings. Changed them still nothing . New icp. New cpm. Now have icp of 66 to 120psi cranking.ipr 14.40 koeo up to 84 when cranking. Ive unplugged just get eratic reading ipr stays same . Please someone tell meive checked ficm 47to47.5 cranking and koeo. No codes beside for my egr delete and when i unplugged icp. Ive been tinkering on thos truck for a couple years now still lost bit getting better. I now have driver valve cover off . Its a 2003 . Thanks guys and God bless.

 

so your ICP needs 540 psi and ICPV .85 to start , I would pull the IPR and check the screen .

 

Sounds like you have lost high pressure oil pump or pressure bleeding off due to a leak in the system.

 

I think hpo leak to. Ipr and screen clean.just had it out when i did injector orings. Clean screen no tears or metal shavings. How are ipr readings i gave.

 

the 1440 at koeo ford has 14.85 so close, what is ICPV?

Robs got you covered. this is where I was headed just trying to rule some things out.

I will check tomorrow on my icpv need to put pid in my sg2 after work or when i wake. I appreciate all the help. I see light at the end of a long tunnel. A seven thousand dollar tunnel😂. Finally heard it a thousand times . Ask for help. Can i ceank with valve cover off. Looks lile braded hpse going to rail has leak at where it screws on to rail end of braded line .

 

There is a long thread when a member traveled down to Louisiana to help a person out. There are pictures in that thread with the part number to the connection I think you are talking about.

SuperDuty service is his handle now. Or contact him at Anthony@sdutys.com

 

Is this where you are talking about. Video is on that page. If it is, read further into that thread and you will find the part number.

Ok finally got my icpv it is .24 koeo and .25 cranking. It anewer pigtail so i dont understNd what that icpv means. Isit low ornormal. Thanks again.

 

Yes thats the line. Mine isnt broken. Just wondering of its a leaker or has orings i should change

 

Icp hitiing 340psi in long crank now
icpv
ficm 47.5
ficm vhicle. 11.5 aand down when cranking long to 8.5
ficm lp 11.5 to 8.5 in long crank
ipr 85% cranking

Long crank 30 or more seconds kills batteries so maybe they are bad. Load tested ok a week ago. So were my batteries giving me bad reading due to being weak. Im puzzled i just want to drive her again. The power was awesome

 

Where ICP is pressure expressed in PSI, ICPV is the actual voltage being read by the PCM from the sensor. Here is a chart (sorry, the format gets jacked up by the site).

Press Press Sensor
(PSI) (MPA) Voltage
0 0 .02v
200 1.5 .4v
400 3 0.73v
600 4 .96v
800 5.5 1.2v
1000 7 1.4v
1200 8 1.6v
1400 9.7 1.9v
1600 11 2.1v
1800 12.4 2.3v
2000 13.8 2.6v
2200 15.2 2.8v
2400 16.5 3v
2600 18 3.3v
2800 19.3 3.5v
