6.0 Crank No Start

- Follow my DIY misadventures trying to troubleshoot a crank no start on my 6.0 Powerstroke. First time using the FORScan diagnostic tools.
I appreciate the work of @AutomedicGarage !

You were only making 280 HPO. That’s why it wouldn’t start not the fuel leak.
So you suppose I still have an oil issue?
And also thanks for all you do. Blessings to you and your family.
@@paggre my guess is your lpo relief valve was partially stuck making it hard to build oil pressure. Or your drain back valve had trash in it letting oil past it and when you cranked the truck without the filter you dislodged whatever it was or your truck was warm when you were cranking with the forscan and by the time you were done with the fuel filter had cooled enough to build oil pressure again which would mean you have a oil leak when hot creating a crank no start hot only.
That makes sense. Maybe I'll clean that lpo drain valve that you showed. Just to see if there's debris.
You definitely have a HPO issue. Your desired versus actual values are not even remotely close for the engine to run. Unplug the ICP sensor and try to start the engine. If engine starts, replace ICP sensor. If not, I suspect a massive leak or a faulty HPOP. Remove IPR valve and pressurize the system. Listen for leaks. If none found, you have a faulty pump. Any parts you purchase, get them from FORD! Aftermarket parts (including filters) do not work well in these Powerstroke engines. I've replaced many HPOP and IPR because the owner decided to save a few bucks on a cheap aftermarket filter......
23:59 did you notice the difference between The ICP desired vs the Actual ICP pressure? The Actual was 274 PSI and desired was 1400 or so. Thats why the engine wouldn't start. You hava a high pressure oil problem. A leak most likely.
I did see that. And thanks for the reply! I took it for a drive to get it to temp. I verified that it was crank no start hot. I verified one last time that the lpo was pumping fine into the bowl. I'm taking it to the shop that did the hpop. Maybe it's just the IPR. Otherwise I'll let them look for the leak. Thanks again for watching and replying.
Oil filters dry cuz once you start turning the cab it drains to the oil pan
Thanks! Now I know.
the return tube in the middle is missing a piece with the spring,,
Hmmm I'll have to look at that.
You're right. Tube replaced. Thanks!!
Forescan not foreskin
Ha. Yeah two different things.
