If you got the codes only after running it with the MAF, that isn't surprising. If you clear the codes and run with the MAF plugged in, do they come back? If the code doesn't come back then I doubt it is an issue with the MAF.
If you hear the main pump buzzing while the car is running, your in-tank fuel pump might be bad. When the in-tank pump goes bad it puts a strain on the main pump which causes it to make noise. Check out this site:

It has nicely documented procedures for diagnosing fuel pump issues as well as how to replace it.
