Checked fuel at filter, primed it, no leaks.
Checked all fuses and swapped the relay around (nothing was blown)
Unplugged main connectors, re plugged em in
Checked harness near alternator for chafe, no damage what so ever

She cranks, but no smoke or indication of catching.

Drove fine all yesterday, and just cranks this morning.

Update, after coming home with a spare car, I tossed the charger on the truck and plugged the block heater in.

Less than an hour later, she cranked right over and acted as if nothing was ever wrong. Da faqqqqqqqqqqqqqqq

My current assumption is super low battery capacity led to a low crank and what not.
