Default No crank no start, starter is good but not receiving signal

Went to start the car two days ago and would not crank, no symptoms prior. Battery and alternator are good, gauge reads 14v and i've also tested both, car also runs and drives fine when push started. Starter is also good, pulled it out and bench tested it, spins and comes out. Swapped high beam and starter relays did nothing, starter relay works on high beams as well. No codes relevant to the issue, only have 2 airbag codes (qr wheel). Checked ignition and starter fuses in drivers side panel. Also did a bypass on the clutch safety switch with a paper clip. All electrical components work when key is in 'on' position, windows, lights, etc.

What i did find was that the connector that goes to the starter does not receive signal when key is turned, used a test light inside the connector. Also got a friend to check with his scanner and it found that the car/starter wasn't receiving the signal of the key being turned.

Could it be ignition related? Or a possible faulty crank sensor? Will most likely swap crank sensors tomorrow just to rule it out.
Any thoughts/help is greatly appreciated
