Hello. I have a 2003 f250 super duty with the 6.0. It will not start! It started off by long cranks before it started. It will not start at all now!, I've replaced the fuel filters, the glow plug module, and tested the ficm. I've also tested all my fuses. All fuses and the ficm check out fine. Where should I go from here before I stick it in the dealership?

Unless you have Auto Enginuity or a really good scan tool, you're pretty much pissin' in the wind. Did the truck lose power and die or just wouldn't restart after it was shut off for the last time? Have you checked fuel pressure? How many miles?

Not dtc's showed up. 120,000 miles, wouldn't restart after shut off

If fuel pressure is good then you've most likely got an HPO issue. With it being an 03, it's most likely the HPOP but without a way to monitor ICP and IPR it's just a guessing game. You could try unplugging the ICP sensor and seeing if it starts. If it does, the ICP sensor is junk. Also, pay attention to the ICP connector. The 03's are bad about leaking oil through the sensor and into the pigtail. With it being an 03, the ICP sensor is under the turbo.

Here is the link on monitors....Write Up: Monitoring the 6.0L PSD.
You could pick up a scanguage II at autozone. You don't have to have an AE, most of the time. Need to read icp and/or ipr% to see if you have a hpo leak. Your hpop could be bad, standpipes, hpop hoses that connect to the oil rails, or icp/pigtail as stated. Generic code readers are not always going to pull the stored codes. You need a good monitor.

I didn't realize the Scangauge would monitor IPR. That's definitely a cheaper route than AE but the AE is invaluable and has paid for itself with the first truck I worked on. Good to know about the Scangauge though.

Yes, i'm 99.9999999% sure it does. Lol. It appears to lack in code reading sometimes, based on other members comments. If the cts could read ipr%, it would be perfect.

I have a ScangaugeII and it does read IPR. Since we're on the subject of IPR, does anyone have a good link that explains the IPR function and what percentages are within normal parameters?

[southend]

Ipr 15-85% / idle-wot. Iirc. It will be variable readings, throughout the driving range, it's basically a regulator.
Idle may be around 24%, can't remember. This is without tuning, tuning may change those up.

I disconnected the icp and it didn't start. So I guess its looking like hpop or the fuel, right?
