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?

What's an injector driver module?
Have you checked your wires and connectors? Is there any abnormal condition on cylinder 2?

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

Hopefully that's good. Does it crank? Or start now?
