7.3 Died while driving

[studwyck1]

2003 F250 w/7.3L Power'choke' started sputtering 3 weeks ago when it was 8 degrees out. I changed the oil and fuel filter and put some diesel treatment in it thinking it was geling or freezing the fuel. This worked for a week.

Upon driving to work a week later on the freeway it did it again leaving me stranded (about 17 degrees out). Would not fire up. I changed the CPS on the freeway and it still did not start. Had it towed to a fleet service where they said the truck was out of fuel due to a calibration issue with the fuel sending unit = 1/4 tank = empty. No codes - I was skeptical. They said when they pulled the fuel filter lid it blew the lid off as if it was pressurized, they said that was kind of odd...

This week it died again with-in one mile of the last incident (about 15 degrees out). It would begin to shake, sputter and then eventually die out just as it has done in the past 2 incidents. This time it would restart, but idle rough and have no power or rev's. I noticed white smoke that smelled odd. When it arrived at the fleet service shop it fired right up for them and has not repeated the problem for them. It produced code 1211 which is oil pressure I believe. They think it may be the IPR valve this time, oil pump or injector o-ring. Oil level is full.

I have a trip to the carolinas in one week and i just dont trust it...any suggestions?

P1211 ICP Not Ctrllable - Pressure Above/Desired

Direct quote from Dieselmanns page:
No/hard start hot or after stalling, usually re-starts after cool-down; Jerky, irratic idle; Possible DTC#'s P1211, P1212, P1283:
Usually caused by low injection oil pressure or regulator (IPR) valve. High pressure oil is used to pressurize and inject the fuel into the cylinders--each injector is essentially its own injection pump. The IPR is a by-pass valve that controls the high oil pressure depending on demand. The ICP monitors the oil pressure in the LH head.
Check for oil in the upper reservoir; it should be within one inch of the top; add oil as necessary. Verify that the correct oil is being used (see my PowerStroke Page for oil specs) and that it is not thinned out.

Would you say replacing the IPR is a good place to start?

I was just relaying the info i would wait till someone more knowledgable or a Tech responds.

Replaced IPR valve this afternoon. Made it to work without a hitch this morning. $250 IPR plus $190 w/labor and a tow So far so good though...

My 02 has the same problem with its fuel gauge as yours seems to. Just below a 1/4 tank and I'm out of fuel.First time I found this out,I ended up walking about 7 miles to get more fuel.

Still have not had time to test it out. My starter caught on fire while sitting in my driveway!!! Currently replacing that now...

Anyone interested in an 03 crew cab?

Starter is fixed. She died this morning again in the same spot...

Dealer thinks it is my fuel pick up becoming clogged by the delamination of the plastic gas tank. I'm cleaning it out this weekend. Stay posted...

[studwyck1]

It wasn't delamination but it was dirt inside the fuel sending unit screen filters! Problem fixed!
