HARD STARTING HOT ????

[Penske]

I have an 05 6.0 psd once the truck has been running for a while 30min to hour at least it does not want to restart. Pulled all the injectors-Good oring for injectors and oil supply tubes-good.New IPr valve and new crank sensor. Still it just cranks and cranks have to wait to cool down before it will restart. Any suggestions

What hapens if you press on the gas pedal alittle bit when this happens?

its never injector o-rings pull the high pressure pump cover and look at the fitting at the back of the pump

same thing only on an intermittent basis. Took truck to dealer in Albany OR, last Friday.
Should have it back tomorrow, was told on the phone that there is "a leak in the high pressure oil sys. and Ford has a kit to repair it". Going to be interesting to see the final paperwork and talk with the service dept guys.
When it gave the problem after several attempts Clifford would start but limp at about 200 rpm with no skinny peddle response, tick over for a couple of minutes ,R's would come up to normal idle as if never a problem.

Finally got truck home, week and a day.
Service writer on duty late Saturday seems to know nothing about the diesel world but here is what the paperwork says they replaced, no real world description of the parts, just Fort part language.
4C3Z9B246D (kit)
CMS5126 (regulator)
W303195 (connector)
3C3Z9433AA (gasket kit)
W302725 (hardware misc)

Also said they found an exhaust leak and replaced
3C3Z6N640AA (gasket)
5C3Z6K854CA (adaptor)
if anyone could shed some simple english language description of the parts and what was done I would really appreciate it.
Truck seems to run a bit quieter than it did although have not had time to really run it more than about 30 miles in short hops.

CMS5126 (regulator)<------------ IPR valve
W303195 (connector)<------------- Dummy rail plug on the high pressure oil rail. Usually the lower o-ring deteriorates, leading to replacement. This is assuming the number was mistyped. The part number SHOULD be W302195, NOT W303195
3C3Z9433AA (gasket kit)<--------------Intake gasket kit. I usually just reuse the gaskets, due to the fact replacement is almost never necessary.
W302725 (hardware misc)<--------------- O-ring that goes on the breather tube into the air inlet, on the breather box side of the tube.

I would be pretty confident that your vehicle is fixed, based on what I see in the list.

This is a very common problem to have on these trucks. Based on the fact that they tend to crack at the flex joint portion, your firewall should have black soot all over it, from the exhaust leak.

Thanks for the translation.
I've read about the stc fitting several places but could not translate the part numbers and descriptions on the work order to what they really were and yes the one part I fat fingered the part number when I entered it.
Made a drive to Cottage Grove this afternoon, did the covered bridge tour with several shut down and restart cycles for picture taking etc, Clifford did well, also averaged 18.3 mpg by the lie o meter for the 150+ miles.
