Do you mind telling us how you tested the FICM?

 

You can't test them by pulling them out. When is the last time your truck was flashed? If not since Nov.09 then you might have it reflashed. The newest flash is reported to help cold starts. While it's getting flashed, get the tech to run it through a diagnostic.

How long since your last oil change?

 

I used the test procedure for the FICM from this site. I honestly don't know when the last time my truck was flashed. I do know that before I bought the truck back in July of this year the dealer claimed that they had just put a new fuel pump and FICM in the truck because they were both bad. I change my oil every 5000 miles and just did change Thursday still hard to start. Guess I will take it to the shop and have them flash it to see if that helps.

 

All we can do then is trust that you did it properly .......

I think the dealership is the best option for you at this point.

 

I have been going through the same thing at work with a guy for 2 weeks on his no start/rough running, Ford dealer took the truck and sent him home with new batteries. I told him they would have to cold start the truck in the morning. With the information I supplied, he has a new FICM now

 

If your glow plugs are working, you should have lower battery voltage for a while after it starts. Mine sits at about 12.2-12.4 while the glow plugs are on, then jumps to 13.8-14.2 after they shut off. Get your multi-meter out and check it. The computer reads oil temperature to decide how long to run them. If I forget I'm starting a diesel, and just crank it over, it will hardly start, even at 40F. Use the glow plugs, and it will start at -5F, although it's not happy about it.

 

New development my alternator isn't working properly just started today. Figures with my luck put new batteries in a couple of weeks ago and now my alternator is only putting out 12 volts. I only bring this up because I was wandering if this could have anything to do with my hard starting problem? I guess I will set an appointment with Schied Diesel and have them test my truck since I am still having a hard starting problem and see what they tell me after I get a new alternator put on.
