Hi im new to the site and not sure how to work it yet, but was wondering if someone could point me In the right direction. I have 2006 6.0 powerstroke, I have done an stc fitting, egr delete, oil cooler, blue spring, ficm is about 1.5 yrs old, new batteries, 4 inch exhaust and a edge tuner but I have only been running on the 15 hp setting or none at all. Lately it has been cranking abnormally long when first starting in the morning, but once it gets warm it fires immediately. Yesterday I was coming home and I revved the engine once and it died but restarted, I did it again to see if it was just a glitch but it died and won't restart now. I have no codes, I unplugged icp to see if it will start and nothing. It cranks perfect, no real smoke out the tailpipe and the oil pressure gauge goes to normal when cranking, just wont start, was running great last few months but now this, any guesses on where to start looking?? Will it still show oil pressure if the hpop is no good? I was told maybe the hpop because it might be loosing oil in pump area while sitting over night and takes a good crank to get it primed. Any help would be appreciated, thanks!
