2009 Kia Sorento 3.3l no start

Hello, I've had my Kia down for about a week. I feel like I've been over everything. When I turn the key, nothing happens. Not even the starter clicking over. I have a few codes popping up.

​U0101 (or similar lost communication code): Lost Communication with Transmission Control Module (TCM).

​P0057: HO2S Heater Control Circuit Low (Bank 2, Sensor 2).

​P0462: Fuel Level Sensor "A" Circuit Low Input.

I had a mobile tech come out and diag it as a bad inhibitor switch. Okay. I replaced that. Which is in the transmission of this car, ugh. Just for funises, I replaced the ignition switch. Still nothing.

I can jump the car from the starter relay, but it won't really engage the cars power. Limp mode maybe? But the starter will engage if I jump it from the relay pins. The relay does click and I've traded it out for the P/W relay to test the relay.

All of that, and nothing. I can't afford to take it to a shop. My wife lost her job and I work Instacart. (She's since started another)

Any ideas? Starter? I've checked the fuses. Everything seems right. Nobody I know has a clue
