[QUOTE="2015sixohno, post: 1435375, member: 22277"] Kinda tough to say where the exact issue is located. You could air leak the oil system when the truck is HOT and listen ( keep in mind it may take 10 minutes for the leak to show up ) but at a minimum just order the stand tubes and dummy plugs. If they haven't been don't it's not if they are bad it's when. When you have the oil rails off the injectors CLEAN the top of each injector and inspect O rings where the nipples of the oil rail seat in. These are very prone to failure and will also cause your problem. Another recommendation is to just replace the IPR ( easier to get to with ficm out of the way ). All of these are just to common to fail to not just replace for piece of mind. Every 6.0 that comes in my shop gets these basics at a minimum if they have starting issues. If you can't find anything under the valvecovers the STC on the high pressure pump is the next place I start looking. Hope this helps ! Sent from my iPhone using Tapatalk [/QUOTE]
