powerstroke wont start if warm!

One or two bad injector o-rings would not keep it from starting. If the IPR o-rings are bad, it won't let it build enough pressure to tell the PCM to fire the injectors. A couple bad injector o-rings would just make it run rough, and most of the time it will put oil back in to the fuel bowl.
IPR O rings are the easiest , most common test .Warm oil starting problems can be as bad as an injector poppet issue.
Either a worn poppet or simply a loose poppet screw .

.Low Hp oil pressure will most times keep the HP oil pressure low enough to keep the IDM from firing .Could very well be injector O rings There is a test for this.

ok I rebuilt the ipr ( the O-rings were no longer fat and sealable ) made sure that the piston in it wasn't sticking & etc. popped it back in and I also cleaned the fuel bowl and the fuel regulators fine screen and they where both very ,very ,very nasty and clogged with trash . I put everything back together and ran it till it got to the operating temperature and it still didn't want to start, so with the ipr and fuel bowl eliminated and unplugged the pcm on the corner of the motor and that cured the problem !!!! it started at operating temperature ,so ill get one of those and go on from there
