Is the gauge accurate? How do you know?

This entire EFI setup is new (as in weeks) including the gas tank and fuel pump (located in the tank). I could look for an obstruction in the fuel lines/filter, but if gauge reading zero while in CRANK or ON position, seems to me the fuel pump has failed.

While not likely, a plugged fuel filter could cause lack of pressure downstream.
Don't drop the tank until you're sure the pump has adequate power. Lack of voltage will make for a "dead" pump. All it takes is a popped fuse, or a loose connection.
