please help hot no start

[notimeforfakes]

Hey, guys. I have been getting help from this site as a guest for a while but I just signed up cause I am stumped and hope to find an answer.

I have an 04 late build 6.0 cc lb fx4 that is giving me hard cold start, hot no start snd white smoke at idle (smells like oil of fuel to me?) I am very new to diesel mechanics but am somewhat mechanically inclined. I have done the wrong thing and thrown psrts at it so far with no avail. I have no codes. I replaced hpop, ipr valve all injector o rings fuel rail orings stabd pipes dummy plugs upgrsded turbo feed and drain tubes. Blue spring upgrade all newfuel and oil filters all oem.

I have scanguage 2 and cold srart takes a few seconds then icp and ipr seem normal both hot and cold, high and low idle. But once its hot snd I try and srart it only builds about 250 pounds of pressure and thst number goes up as she cools down untill it finally hits 500 and srarts up

I have charged ipr and hit it with air and cant conclusively find any leaks

Please help. I cant afford to take it in right now

Anyone???? I removed oil filter after I brought her up to temp and had buddy crank. Took 10 seconds to fill oil filter housing with oil so I believe I have low pressure oil

CAN U ACESS EOT AND ECT ?

USALLY HOT NO STARTS LEADS TO H.P OIL LEAK. I WOULD DOUBLE CHECK THE DUMMY PLUG CHECK ORINGS (HOPEFULLY THERE THE UPDATED ONES WITH A WHITE TEFLON ORING AND REGULAR ORING) HOW LONG DID U DO THE REPAIR BEFORE ISSUES OCCURED?

sounds like a classic high pressure oil leak, although 10 seconds to fill the housing seems a bit long (no idea what is righ though).

You replaced the HPOP? so I assume it came with the new fitting to replace the STC fitting?

May want to throw a gauge on the low pressur eoil and very that is adequate. Other than that it sounds like a leak. May want to repeat the air test.

Thank you so much for the responces. Yeah. I am thinking its a leak too. The question is where. D plugs and standpipes are brand new updTed with the tephlon washers

My last effort (I hope) is to pull the turbo and check the o ri g where the discharge tube meets the branch tubes. That is the only oring in the entire hpo system that I hav3nt replac3d. I will keep you posted.

Anybody know how to remove discharge tube from branch tubes???? (

[sinner6.0L]

it's a quick connect fitting, there is a special tool but it's not necessary. two small flat bladed screwdrivers can be used to release it.

Thanks but I apppied air to the top of the discharge tube and cant hear any leaks. System seams to be air tight???? Anyone????
