The car drove fine last time I started it (2 weeks ago). Today, I started the car remotely. It started for a second, then shut off, and then wouldn't restart. I seem to have P1516, P2102, P2119 and P2135 codes persistently. I charged battery and it seems to be fine, but the starter would not engage. Got an "Engine Power Reduced" and an "Engine Disabled" warning on the obd. I inspected and cleaned the throttle body and there doesn't appear to be any issues there. I reset ECM by shorting car's positive and negative terminals together for 15-20 minutes. Starter then worked when attempting to restart but the car did not fire. The issue must have immediately logged another code because the starter would not engage a second time. All codes returned and my diagnostic tool doesn't seem to successfully delete them, even though it states it does. Presently resetting ECM again with no idea where to go from here... Thanks!
Update: Car now starts but runs very roughly. Engine in reduced power mode. Still some kind of issue, whether it's a relearning issue or not, I'm not sure. Only codes now are P2119 and P2135!
