A couple days ago it took more cranks than usual to start, and then the next day it wouldn't start at all no matter how much it cranks. Later I tried again and it eventually started up, but I couldn't get it started again after that.
Checked battery voltage and it was good. Checked spark plugs, they looked good. Finally got a P0202 and P2201 code, description says Injector Circuit malfunction cylinder 2 for P0202and NOx Sensor circuit range/performance bank 1 for P2201.
Someone else told me it could be the direct injector driver module but I'm trying to figure out how I can find out for sure that that's the issue. How can I test it?

I'd never heard of the IDM before either but I picked one up for $20 off a part out car just to see if it did anything(it didn't) and tried a new BlueDriver OBD reader and got no P0202 or P2201 but on live data it says the fuel system has an open loop due to detected system fault
