trouble with a 2003 6.0

[knoxemt1983]

hey guys, I am new here but have been lurking for a little bit and can't seem to figure out whats going on with my truck. It is a 2003 f-350 with the 6.0. It runs super rough when its cold, and sounds like its about to die, and actually has once. I just bought the truck about a month ago and it the problems just started. It also is chipped, with a superchip, but I dont yet know what model, and has 4" straight pipe.

Here are the trouble codes, and what I have been able to dins on some of the
p2269 water in fuel (I drained the tank twice, and it is still on, no hesitation and 3 tanks of fuel since)

p0603 Internal Control Module KAM Error
p0678 Glow plug #8 circuit failure (replaced #8 glow plug last week)
p2285 ICP low value (I know I probably need to change it under the turbo, no warranty)
p1000 incomplete read

P0603 is being caused by the superchips....and is normal

the ICP code is going to be a sensor leaking oil. That can cause a running rough condition, but i woudl take it in the dealer and have the latest PCM programing put it it so you have the inductive heat staratagy for your injectors.....sticking injectors are the most common reason for a cold start miss and the later programming fixed about 95% of trucks. Do that and check into the ICP and you should be good to go....

Pull the 6mm plug out of the lower fuel filter housing...thats where you should drain the water from to prevent the water in fuel light...

yeah I drained it again this afternoon, and changed my fuel filter, but the light came back on after I reconnected the batteries. thanks for the reply, I will take it to the dealer monday.

I also have the same problem with the water in fuel light. My check engine light came on and had it checked by dealer. They fixed the ICP sensor. I asked them about the water in fuel and they told me that the manifold for the seperator needed replacing. $300-500. I told them I would wait.Curious to see what you are told. Send me a message if you dont mind.

you need the water separator manifold with updated wiring

since there not free anymore they can get expensive with labor and all. You can try taking it off and cleaning the inside with brake clean if you want. Around the old heater there can be a lot of slime and gunk built up.

I was at 2 Dealers Monday and the Service managers were not aware of the PCM flash to fix the cold starting problem, that I have with my truck. So far I've learned how to start it without downing the batteries. Pedal to the floor and let it kick till it start Idling on its own. But It hardly turn a few turns before it starts to kick. I do have the feeling that this is the Flash I do need because in the instructions it states that the injectors cycle after the engine is turned of to clean itself, and be ready when a cold start will be required. and mine don't do that.

When was the Inductive Heat Statogy installed in your trucks.

[knoxemt1983]

so just to upadte everyone, I took it in to the dealer today and they are updating the computer, fixing something that they said was recalled on the injectors, and replacing 2 glow plugs. So we will see how all that effects the cold starts.

from what I was reading, the newest programming doesn't cycle the injectors after the ignition is turned off. Is this correct?

thanks for helping a nu-b out

Correct. Ford uses the inductive heating stratgey now. The spool valve coils are used to heat the oil around the spool valves to keep them from sticking on cold starts. It's supposed to be good without plugging in your block heater down to something like 10*F.
