Id check your fuel pressure regulator. You need to get another fuel pressure gauge though to see what its at right now with the new pump.

Ill post here as well as the PM I sent.

This is what i would do in order.

-Buy a pressure gauge
-Check voltage at fuel pump
-Replace corvette filter/regulator because its cheap and if that isnt it youll use it in the future anyways.
