Exclamation 6.0 No Start???

Live in middle Tennessee and woke up two mornings ago and it was 28 degrees, 05 6.0 cranked right up fine (was not plugged in, no block heater). Drove 50 miles shut truck off for about 30 min started again fine. Drove 5 miles to local hardees for breakfast, get to the drive thru and turn truck off to order and it wont start back acting as if batteries/alternator was problem. Pushed truck out of drive thru and pulled batteries and took to advance auto and charged all night and tested good. Took batteries back and put in truck still very slow cranking. Hooked up a set of jumper cables to each battery and hooked to 06 cummins. Let set for 10 min tried to start still nothing acting as if batteries are just weak, then hooked 2 large fully charged Snap On jump boxes to each battery on top of the cables. Nothing. Not exactly sure what the problem might be, the obvious would be bad batteries but i feel that it could have something to do with my ficm but not sure. PLEASE HELP ASAP! Need truck back quick as possible. Any help would be greatly appreciated.

I am assumeing it won't crank [roll over] if the batteries are indeed good you may be haveing too much draw while cranking, bad starter dirty cables etc. The FICM has nothing to do with this.

If instead it will crank and not start you need to have it scanned on live data and watch your ICP pressure [500 psi min] to start. IPR % FICM volts in and out and see if it makes sync This will be either yes or no or 0&1 depending on the scanner

You can also try a field test unplug the ICP connector and try to restart. If it starts and runs you had a bad sensor or pigtail. If it doesn't you have a HP oil system leak.

Lord I shall lead them to the water but I will not try to make them drink
