Please Help ASAP Very Urgent

[dleopard19]

ok so i have an 04 6.0 and lately when i first start my truck in the am and drive to work and gets good and warmed up i shut it off then have to deal with a no crank, it turns over fine but will not fire up, but if i let it sit all day then it fires right on up. When i get it warmed up though and drive around i cant shut the truck off or ill be stranded in the same spot for a couple hours. I took the oil filter cap off and bumped it over to see if i was gettin oil pumped into the housing and i was but the oil would slowly drain out of it. Initially when i pulled the cap off after it had sat a couple hours the oil filter housing was completely empty. Can someone point me in some direction cause i need to get this issue resolved asap, my job requires traveling so i need some help asap, ill even take phone calls if necessary just to get a response lol 9016195173, my names danny, i will also be able to explain my problem better if its hard to understand on here. thanks.

Sounds like the STC fitting maybe . Cold oil won't leak out of it as fast as warm oil will, that's that argument. Ford has an updated one now I guess. Do a search, I'm sure you'll find what you're looking for

04's dont have STC's fittings. But I would say that you have a HPOP issue, leaking pressure, typically when they leak pressure that result in a no start hot issue.

I did not know that, I thought it was 6.0 thing. I learn something everyday

so should i rule out the low pressure oil pump?

You need a diagnostic tool to measure your ICP and IPR when it is cold (to get a baseline) and then again when it is hot (to determine what is going on). Do you have access to a Ford IDS, a Snap On tool or AutoEnginuity?

i have a snap on modis tool

hey abrannon19 you were talking about the hpop leaking pressure off. when i shut my truck off & then koeo is my icp pressure suppossed to start leaking off or should it remain where it was i am having trouble with a slow start, random no start. mine is an 03

Yes the STC (snap-to-connect) fittings started being used in the '05 model 6.0 so the'03 & '04's don't have that issue, but, more than make up for it with ther rate of HPOP failures.

alright guys just an update i fixed my truck yesterday and it ended up being my standpipe under the passenger side valve cover on my high pressure oil rail. I got the new updated pipe from ford replaced it and now running like a champ no matter hyow hot it gets and never cuts off while driving anymore, if need any questions answered ask.
