2003 6.0 running rough, no power, white smoke etc...

[Diesel1050]

Well i'm getting pretty annoyed with this. Have a 2003 F-350 6.0, that over the past week has been running worse and worse, to the point where it is barely driveable. Did oil change done recently with 2 bottles of Rev-X, just changed fuel filters, truck has 126k on it. Recently had the ICP go, so I cut the wire to it and it stopped the stalling/rough idle issue. Fast foward a month, and it suddenly blows a bit of white smoke at startup (Definitely from diesel, not coolant/water), and has NO power, NO turbo etc. Thing barely shifts (Have to let off for it to shift). FICM reads 48.5v at idle, EGR is good (Pulled it and cleaned w/new O rings. At this point i'm thinking bad fuel injector (s). Any thoughts? Also it seems since i've owned it the turbo really hasn't functioned properly. Doesn't act like an '03 turbo should....

Sounds like injector failure. Need to know icp readings and pull a power balance test.

But if I was you if you pull one from one bank pull the all.

I would also check your MAP sensor located on passenger firewall small hose going from it to the passenger side of the intake manifold. I've seen holes in the hose and/or hose not seated correctly giving false pressure readings causing severe lack of power. I would definitely do a contribution test though. Any codes apear when you scan it ?
