neither code will prevet the car from starting. 442 is an evap code and 1416 is an air pump code. these can be addressed after the vehicle is repaired.
you need to have the basics checked like fuel pressure and spark. a shop can do this with a scan tool and identify the failure.

Those codes aren't keeping the vehicle from running. Is it cranking or just not firing up?
