OK please send winning lotto numbers for next powerball Seriously, I'm up to my friggen eyeballs of stress. To boot, I jumped into my truck and it started and then died. 2003 F350 SD crew cab 6.0 liter. I bullet proofed the engine 3 years ago, no problems to date.....till today. I went to plug in my torque app and I had no profile so I had to make a new one. Torque pulls up....p2291/p2623 Injection Control pressure regulator circuit open/low. IPR, right? Now, where to get the tool? Also, can I flush the IPR and replace the scene or do I need a new one? I"m at my wits end!!! Working on the wife's car and I'm covered in tranny fluid, trying to clean the house because we are selling to down-grade and I"m just overwhelmed!

Anyway, I need some help finding the info and tools I need in a hurry for a cheap price. Any help would be appreciated!

Thanks

 

Flush the irp?
Replace the scene?

 

That is my first thought too. FLush the ICP. What fluid should I used to flush the ICP control valve? WD-40? Brake cleaner??? I'm not sure because it's a diesel and I've heard brake cleaner can really damage a diesel engine. I assume brake cleaner will work fine, just being extra careful, my F350 is my baby

 

OK, I got home from work and I attempted to connect torque and my blue tooth which worked fine. Unfortunate for me.... my batteries are not so good all of the sudden Currently on battery chargers and batt's are about 1 year old. Granted, my truck sit's for the most part but I drive her once a week. guess I need to invest in a battery tender because I know that bad batteries can mess up the FICM.

Anyway, I did get the truck to attempt to turn over and I got some codes;
P2291 ICP too low engine cranking &
P2623 ICpsi reg circuit open

From what I've seen on youtube, on the 2003-04's this is usually the ICP control valve stuck or failure, correct? I am just hoping it's not the HPOP! I will have some better numbers later once my batteries charge up, but my ICP was under 500, i think it was 200 psi and my IRP was 83% My FICM was 48.5, FICM sync was @ 0 but I suspect the refresh rate for now, hoping I don't have any other problems.

Thank you for the help

 

OK, batteries charged to full;

FICM 48v Good!

FICM sync 0???? I"m not getting a code for this so I"m hoping that it's a refresh problem vs cam sensor problem

ICP = 200 max I hope it's not HPOP! I have read that 2003-04, most commonly IRP valve stuck

IRP = 83.9% + leak of some sort.

Any thoughts, ideas, or direction on this headache ????
