won't start when cold

I have been having a problem with my 6.0 starting when its cold, temps below 20 degrees. The motor will fire but won't stay running. this goes on until the batteries are dead. Please help.

i had that problem... and it turned out to be my FICM. now, it starts and idles nicely in 20 degree weather.

Yuuuuulp.. Classic FICM issues..
I'm lucky that mine clears up after it warms up.. (But it's DEFINITELY running on borrowed time.. lol)

YouTube - Rough cold start.. Rough idle.. Rough everything....

I have an '06 6.0 and it started off with just hard to crank. But now it's not starting up at all, it will fire off but not start. I did find a small fuel leak at the top fuel filter cap and hoping that may be it. I know that could be a long shot but I'm gonna try anyway. The Ford tech. did mention something about the FICM if all else fails. Any suggestions out there, and is the FICM covered under warranty?

Had truck towed to Dealer and they found a bad FICM. It was covered under warranty thank goodness. Next thing is to try improve my MPG. It sucks! Low teens is not good.

FICM issue for a rough start? This blows. Looks like something else I may be getting.
