None of those codes point to fuel pump or spark plugs. P0113, Is the MAF sensor plugged in? The other three have the vent valve in common.

Are these codes historic, pending, or current? (Status)

Are these from a recent read, or from before work was done?

MAF has been changed twice and it's definitely plugged in

https://www.obd-codes.com/p0496 Is for the purge valve. You can’t blow air through it? In either direction?

Yes EVAP vent valve

https://www.obd-codes.com/p0113

The device is the MAF sensor

Faulty vent valve or purge valve

All can be related to loose wires, chaffed wires near the purge valve bracket under the hood.

The IAT and the EVAP purge valve are on the same fuse.
I would be looking for a rusty EVAP tube. And a wire ti the MAF. P0113 could be caused by 2 wires making contact. , it indicates a short circuit.
