I ran wires directly + and - from battery to pump and I can hear pump running.
Is the fuel pump being turned on ? Is there B+ voltage to the pump ? Check fuel pump relay , check the basic before condemning a new fuel pump ! Videos on youtube , buy a fuel pressure gauge an a volt meter an test the fuel pump electrical circuit . You can look at free wiring diagrams at http://bbbind.com/free_tsb.html We test not guess 04 Mazda 3 Fuel Pump Diagstravaganza How to test an electric fuel pump Check out a few videos
New pump may be bad--it happens. There should be a check valve that keeps fuel from draining back when you turn it off. If this is not working it could cause this.
