My car won't start and was hoping the community could suggest where to troubleshoot next. What follows is a rough breakdown of my efforts so far.
Car was struggling to start for awhile now. Took the battery to AutoZone and it tested as bad, replaced on warranty. Starting improved, but was not fantastic. Car barely started (slow cranking) at 17°F with battery voltage at 12.1V. Drove to my GF's and the car was running fine, but now after sitting overnight it cranks without starting (22°F) even with booster box. Applied a trickle charger to keep battery fresh during subsequent attempts.
Info from various attempts:
Ambient Temperatures: 17 - 40°F
Battery Voltages: 12.55 - 12.1
Battery: Duralast Gold 94R - 985CA, 790CCA, 130Ah Reserve
Starter: Autozone, a few years old
Voltage Drop (to starter): about 0.79V and 0.75-0.82V with a newer clean cable from junk yard
Voltage Drop (to block): 0.1V
Glow Plug Ohms: all four at 1.8 Ohms
Glow Plug Voltage: battery voltage
Starting RPM (VCDS): 100-185
Fuel cutoff: Actuates with key on
Fuel Line: Bubble about 1.25 inches long
IQ during cranking: 29.5-35.4 mg/s
VCDS Injection timing: Dead middle of graph as-of a few months ago
VCDS DTCs: None relevant
Oil: 0w40 Liqui-Moly Synthetic
Mods: EGR/ASV deleted, Kerma tune, R520 nozzles & 17/22
If anyone has any suggestions of where to look next, I would appreciate it.

I'd lost prime on the fuel system. There was a bubble at least 1 inch long in the sight tube and I couldn't see fuel in the filter which was a good indicator. Futzed with the thermostatic tee and rebled the lines to get it running. Also refreshed battery/starter/glowplug electrical connections for good measure.
