stroke has the flu!! do i need more injectors

ok, heres what ive done and what the truck does.
at cold start-up, truck smokes like im burning pine knots. i think glow plugs but we'll see after this is over. staring when warm, still smokes (although not as bad as cold). sitting at stop light or idling the thing still smokes. smells like fuel, an eye burning fuel smell. when im driving its loud. almost like the its a woodpecker under the hood. runs and idles rough. not a lot of power especially if im towing. cant hear the turbo run. doesnt burn or leak oil or coolant. cant see any fuel in the coolant overflow so i think the sleeves are ok. truck has 265k on speeder-meter.
what ive done. pulled valve cover on driver side and pulled injector plugs individually and #8 made no change in engine. changed injector #8 and no change. took to shop and ran buzz test and checked for codes (since mine wasnt showing a check engine light) buzz test passed and codes show cylinders 2,4,6,and 8 were not communicating properly..forget the actual code number but the shop guy says the uvch needs changing so i changed it. NOTHING DIFFERENT
i dont want to be like some of the others in here chasing their tales replacing everything for no reason. i wish i could afford it but i got diesel taste and a gas burners wallet. i do what work i can myself.
where do i turn? what do i do? any help in here is greatly appreciated. i just want my 7.3 to run right. i miss it. thanks all

Check the uvch on the outside of the covers. On the engine side too.
Could be idm if you get all codes

I made my Samsung SGH-I997 send this.

IF IT AINT BROKE DONT FIX IT!

do not cut up your harness if the wires look good.

also... do not go grabbing at the injector wires unplugging them again. that is 150V DC running through there... its enough to kill you... or at least hurt you bad.


what is the temp outside?
how old is the fuel?
open the fuel filter bowl and check out the filter (if nasty replace)
is there trash / rust in the bowl? how does the fuel look?
is there oil in the fuel bowl?
inside the drivers wheel well is the IDM (Injector Driver Module) just behind the fender at the F350 badge.
pull the plug and check for corrosion. Pull the IDM and shake... if water is inside you need a new one.

you need to be REAL detailed if you want more accurate replies.

Keep us posted!

yup that's a bad ICP.

clean the plug up and get a new ICP in there... that the first thing I would do...

a bad ICP can cause a no start... so even if it does not fix the issue its good preventative maintenance.
