k20 cranks but won't run diagnostics

Hey hondata people,
I need help figuring out why my EP3 will crank but won't run. History the car ran fine and I parked in the garage and the next day it would just crank and not start. Attached is a log I made of me trying to crank the car a few times, was wondering if anyone might spot something wrong.
Self Diagnostics:
I've checked every pin in the ecu manually and haven't seen anything wrong as far as voltage and have load tested the main and fuel relay for voltages and they are operating correctly with proper voltage when engaged. I've replaced the following sensors/parts with new oem Honda parts: crank, cam, map, TPS(calibrated), and ELD. I can hear the pump turn on when someone puts the key into on position, so I'm assuming the pump is working. I pulled the fuel pump fuse and attempted to do a spark test, but did not see any sparks which leads me to believe it was some sort of ignition issue.
My guess:
I think it's something related to the immobilizer, but I do have it turned off in kpro. Also noticed the green key light never turns on. Could a damaged immobilizer prevent a car from starting while its disabled?
kmanager: 4.4.3 kpro: v4 (white board) ecu: 37820-pnf-a03 Thanks,
Dimitri
