How long does the engine crank before it starts, and also how fast does it build icp pressure?
High pressure oil leak is a common failure on the 6.0. Easiest way to check it is to pull the valve covers and check for excessive oil coming out of the rail while idling. The leak could be an injector nipple, cracked oil rail, loose plug in the oil rail. It can be troubleshot with the valve cover on but requires a lot of expensive tooling. If you need anything else just let me know
