Hard startr after hot after it sits for 30min-1hr

[Bad-Duvall]

I did use the search. and didnt find really what this truck is doing so.

Truck runs good and starts find when cold, when hot, just wont start after you let it sit and it starts to cool down. 30min-3hr.

if you crank on it long enuf it will try to start and run really rough. hold you foot on the throttle and it may all the sudden jump to high rpm 3500 or so .

Icp pressure are correct 700 while cranking and 3k++ while max throttle.

any things to check?

My brothers truck did the same thing. High pressure oil leak and when the oil was hot it couldn't build enough pressure. His happen to be the oring on the top of the injectors (2 new napa ones with less than 2000 miles). Replaced the two injectors and its fine. When it's hot and won't start fire it on ether.

I'm thinking FICM but it could be a number of things wiring, ckp sensor, pcm,ficm, or failing tone ring (one non servicalbe pice of the front of the crankahaft
