No Crank No Start 2014 LT

Hello, I am at the end of my whits. THIS IS SO FRUSTRATING!! My 2014 Cruze 2LT won't crank or start. It was driving really rough, so I decided to check my coolant. (I've been having to top it off too often.) So I replaced the coolant reservoir and attempted to do a radiator flush. My hoses were so gunked up I had to replace a couple of them, and then I checked my thermostat. There was a different color coolant (one I had used on 1 side of the thermostat MONTHS ago/thousands of miles prior) and my radiator hadn't gotten any coolant for that long. Amazing she still ran as long as she did... Anyways, after replacing the thermostat- she wouldn't crank or start. Shes thrown me 4 codes... P1101, P0171, P015B, P0097. Since then I've replaced: MAP sensor MAF sensor Lower oxygen sensor Starter Battery Fuel control module Battery fuse box distributor Starter relay Starter fuse A few months prior I replaced the turbo, accelerator sensor, and throttle body. All fuses and relays are good. Any help or suggestions would be deeply appreciated because I need my car ASAP so I can get to work. Thanks!
