Fuel pump/injectors/computer flash
Posting my own thread....as there are about a million different FICM threads out there....
I have a 2003 F350 6.0. In the past year I've had stumbling issues after a cold start-up that go away after the engine warms up. Recently is has gotten worse...meaning that it takes longer for the stumbling to go away. The other day I noticed that even after being fairly warm, she was starting to blow smoke while excellerating. This morning she did not start. First time ever. Temp was 34 degrees out. While trying to start she blow a god-aweful amount of white-ish gray-ish smoke. I tested my FICM as per the test procedures on this site. All voltages were between 46-48 volts from KOEO to and through starting. This tells me the FICM is fine and that my issue is with the glow plugs and/or injectors. I guess I'm headed to the dealer tomorrow after work. I really didn't want to pour money into her right now as I have other stuff going on, but it is what it is.......
EDIT:
Please read below for more info from dealer......

I never checked beyond idle once I finally got her started yesterday.
What seems to be the going rate for replacing injectors at the dealership? Parts/labor? I've always heard that one bad one equals a rough running truck and two bad makes for a hard to no start situation.....that seems to be where I am. Could it possiblybe more than 2 injectors? I just want to walk into the dealer with as much knowledge as possible.
Also...with the FICM testing good, what tests should they be performing next to check injectors and glow plugs?
Thanks in advance! I'm headed to the dealer this afternoon after work.......

I've always heard they won't run with more than 2 injectors bad and the dealer told me the same thing today when I dropped it off. We talked about the FICM test and agree that is good. I should know what they find within 48 hours.....told me a quick estimate on 2 injectors with labor is around a grand...sound about right? They only told me this as I asked what it runs. Obviously will wait into the tech looks at it.

When I bought my 04 350 in Sept I found out it had 3 completely failed injectors. The dealer was going to charge me $1500 total to replace them. I called a local shop and they suggested buying a set of Stock+ injectors from Warren; 8 injectors for $400. They gave me a discount on labor since I'm a firefighter and that only ended up costing me $400 also. So I ended up getting 8 injectors (equivalent to about 155cc) installed for $800 total.

Before taking it in to Ford, I'd strongly suggest re-testing the FICM voltages when the truck is stone cold. Another sure fire way to determine if it's the FICM causing the no start is to heat the FICM up with a hair dryer (NOT heat gun...), and then try starting it. If it fires, you know where your issue is.

Warren is a company in PA. They specialize in 6.0 injectors. I hadn't heard about them until I contacted my local shop. They completely strip down, clean, and rebuild injectors. Their site says they go up to 225cc's.

I tested it stone cold and it tested fine...trust me, I was hoping the FICM test would fail so I could send it to you to fix, as that would have been cheaper probably. We'll see when they call me. If for some reason they tell me its the FICM, I'll pick up the truck and ship the FICM to you for repair!!
I'll up date ya'll hopefully tomorrow afternoon......till then I'm riding the Harley everywhere!! (not that that's a bad thing.......)

I changed the title to gauge more help...
The dealer just called and said they need to replace the fuel pump due to real low pressure. It is too low for them to get an accurate test on the injectors. They also want to reflash the computer as I still have the OLD buzz flash (yeah yeah....I know its REAL old).
What do ya'll think?? Will this solve my problem, or just be step one where they come back after and say they now want to change out xx number of injectors for a bunch more money? They want 840 bucks for the service to include diagnos, fuel pump, and reflash...

Sorry, but that's BS IMHO. Sounds like they just want to sell you a pump. What happens if they sell you a pump and it doesn't fix the "low" fuel pressure? And after all.......it is a FORD modification, not something aftermarket. It's not that hard to change a pump and/or fuel spring yourself. You could have them flash the truck and take it out. I'm not too much on dealers that have their own engineering department and know more than Ford.
