Dead batteries, bad tumbler... I think we're going to need a little more info. Does it turn over? If not do you hear the starter click?

Look in the tech folder at the beginning of the 6.0 Forum. There is a thread there that describes how to diagnose a no start condition. You should also read the thread about FICM repair/replacement and how to check it's voltage. Check your invoice on the computer they put in. It should have a 12/12 warranty. Were you able to get it code scanned before you replaced the batteries???

Just to add to the above, I would focus on wire harness chaffing, maybe a bad ICP connector, or maybe a fuse or relay is not seated properly (chances are that it is not psd junk).

Well there is a 10 amp fuse next to the firewal on drivers side where there are relays and one other fuse . Yesterday before i tried starting it i had pulled the 10 amp fuse out checked it it was good so i put it back in that's when it started up no problem. today i pulled the fuse out tried starting it does the same thing it has done in the past just turn over and over. so I think i have narrowed the problem down somewhat. ......ANY IDEAS NOW

If the fuse you're refering to is under the hood it is for the FICM. A FICM relay is also there that is powered by a 50A fuse from somewhere. You can see the relay in the top center of the attached picture.
