With these codes, one of them is telling us there may be low or no fuel getting to the engine, can you see if the engine will start using starting fluid? If so, it sounds like the low- or high-pressure fuel pump has gone out. If you turn the ignition switch on without cranking the engine over, can you hear the fuel pump in the tank turn on for about 5 seconds? If so, it could be the high-pressure fuel pump.
P0131 - O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1): This code suggests that the oxygen sensor in bank 1, sensor 1, is reporting a lower voltage than expected
P219A - Bank 1 Air/Fuel Ratio Imbalance: This code indicates that there's an imbalance in the air/fuel ratio on bank 1 of the engine.
