Hello. The mass air flow sensor would definitely cause the car to not start. It needs to detect the right amount of air entering the engine to be able to run.

Due to the codes you are getting, the sensor should get it running again, assuming that there are not any electrical issues with the car. If you want to have this repaired, consider having the car looked at by a certified mechanic who can diagnose why your car won’t start and repair it accordingly.
