6.0 lots of grey unburnt fuel smoke

Ok so I haven't been on in awhile but I've got an issue that I think I kniw the answer to but would like some more opinions. Truck is an 05 155k deleted no studs yet pretty stock. Truck has new 550 miles warren diesel stock injectors. Ran great for the first 549 Miles then all of the sudden started running like crap and acting like it had an injector issue and pooping unburnt fuel smoke thick and grey. Fuel psi is where it should be at around 60 psi. Has hi flow banjos. Icp is around 1 200 psi cold at idle and never below 600 psi at op temp at idle. and ficm voltage has never dipped below 48.5 volts. So as you can see I'm kind of stumped I've always had awesome luck with warren diesel injectors so I find it hard to belive that they are my issue but if it is I guess they are still warranted so not a huge deal.would just like to get some input on this before I tare it back down again. Any help is greatly appreciated

Also forgot to mention no codes at all and I already pulled the injectors thinking that I may have fd up an oring on install. Not the case all orings were perfect.

Re: 6.0 lots of grey unburnt fuel smoke

that should do it. check all wire plug connections, if their all good I'd have to agree there is an injector problem.

Re: 6.0 lots of grey unburnt fuel smoke

Sometimes when you first start it it just kind if starts out with a nice little blue haze then turns into full blown smoke. It does seem very doggy in the low end but if you get on it it runs like what it should except that the smoke doesn't clear up at all
