I am looking for help and suggestions for a 2006 6.0. It will not start when warm. First tear down the stc was replaced along with new fuel tubes. Problem not fixed. Second tear down new dummy plugs installed, but drivers side standpipe/fuel tube would not come out. What cold be preventing it from moving? Problem still not fixed. Please help!!!!
 
I would point towards Hpop possibly
What's high pressure oil cranking psi?
 
Just had a truck that did that and was the vavle under the turbo the seals where shot. Can't think if the name of the vavle

Yes it was that the seals around it where bad. They ran air through the system and heard it leaking and replaced it works great now.

Could be injector o rings also, you need to know if it's building high pressure oil when it's in the no start condition.
