2003 6.0L Won't start when hot (sometimes)

Engine starts fine when cold, but sometimes after driving it for a distance sufficient for it to warm up it will not start. Starter turns motor fine. One time when it wouldn't start, I disconnected the batteries for 15 minutes and it cranked. It has acted up since then, and as I work out of town and my wife drives it, I have not been able to try this again to determine if the act of disconnecting the batteries temporarily solved the problem or it was merely a coincidence. She has taken the truck to a local Ford dealer who have duplicated the starting problem but say that they can't get an error code to come up on the computer. They think it is the fuel pump, but from what I have been told have not put a gauge on the fuel line to confirm their diagnosis. Has anyone else experienced this problem, and if so offer their solution. I have read and forwarded to the Ford mechanic the Troubleshooting a "no Start" condition list from this site. Thanks in advance for any help.

Not saying it is from here but the 03's are notorious for ICP problems causing this.

Have you got your truck fixed yet? Did they finally put a gauge on the fuel pressure test port?

I went round and round with a service manager when my truck was haveing issues with the HPOP system. I wanted them to put a gauge on the HPOP and they refused stating "Ford doesnt recommend using a gauge." How stupid could they be? Or how stupid do they think I am?

Anyway, I finally had to fix it myself. Never again will my truck go to a dealer.

To make a long story short, my HPOP had a blown o-ring and thus wouldnt make full pressure when oil was hot. Stone cold it would start but not when hot. P2285 (Low ICP) would only sometimes show up.

I now have mechanical gauges on Engine Oil Pressure, High Pressure Oil, Fuel Pressure and Coolant temp. I'm hoping Santa will bring me some more goodies.

Definitely check icp voltage koeo, these are a huge issue on an 03 with the icp sensor located under the turbo. It is usually worse with engine hot also. Check your icp votage with a scan tool with key on, engine off when it is hot. Should be between .18 and .24 volts, anything lower is no good. Also, crawl underneath an look up at sensor (left hand side of vehicle, above bellhousing) to see if it is leaking, this is another indicator the sensor needs replacement. Replace the sensor AND connector at the same time.
