Truck wont start once it sits for a few days, its been in the lower 30's here in MI lately. I can crank it till the batts die and nothing, no smoke no studder. I recharge the batts to full and plug in the block heater and usually by then the temps have come up to 40-50 degrees, I try and start it again and it fires right up?? Never had this problem before, it used to start really good in the cold, never "had" to plug it in and rarely did. Just ordered an SCT so I will be able to pull codes in a few days.

haven't tested glow plugs as of yet still working on it but it sure "buzzes" when you flip the key on.
looking for some pointers if ya got em
truck runs fine at the moment, no rough idle??
just re tested the FICM after sitting for 2 hours with no block heater on and its 55 out and when you turn the keoe and the buzz cycle starts it sits at 15 then jumps to 48 and when you crank it, it stays at 48 but falls to 29 when the truck is running?? Bad ficm?
