Hard/no start hot injector question

[Canadian6.0]

04 6.0 late build. Starts great when cold, warm up to operating temp and let sit for around one hour, then takes a few cranks and sometimes wont start at all until it sits for a few hours. When it does start, lots of white smoke (raw fuel) for a minute or two. Could a bad injector be causing this, and flooding the cylinder while hot? Thanks guys!

Do a search for "no start hot" and you will come up on alot of people with the same problem. I think theres a few possibilities but I think the IPR sensor was the most common answer either that or the ICP sensor I always get those two mixed up
