Where can injection pressure bleed off at?

The shop says my icp/icr are reading and working fine and that my problem is that somewhere along the line my truck is bleeding off the injector pressure to where the truck doesnt want to restart after its warm, and while runing its still missing and not at full power.

I just swapped out my 275's back to the stockers and this problem really appeared. With the 275's it would stumble on a cold startup then clearup after a few minutes or restart it and everything was fine. Now it sometimes fires right up or cranks for quite awhile then misses pretty bad. But there isnt any white smoke like its done before like when its gone thru bad injectors. But it has gotten so bad to where the truck is down on power and not reliable at all so I need to get this figured out immediately.

What is most common and where do I start?

What is your ICP Pressure and your IPR dutycycle when this occures? More than likely the tube right off the pump isbrolen...common problem with the early 6.0's Shop cost $3,000.00+ the whole topend has to come apart..

if you dont have any high pressure oil leaks at the rail or stand pipes, you more then likely need a new high pressure oil pump and J-tube

Im still waiting on another update. Last I heard was that they changed 2 injectors and it was running a ton better.

When I drove it there the truck was running pretty good besides a miss you could hear thru the exhaust but the truck wasnt smoking, bucking etc.. it wasnt even white smoking like when an injector would usually go out. maybe I lucked out, just gotta wait and see.
