Are you sure it is not an injector circuit problem, rather than fuel not getting to the engine?
If the new pump is not turning on to pressurize the lines when you turn the key to on, not start, you will have to do some electrical testing of the fuel pump circuit. A fuse and a relay will be in the circuit. Do you hear the pump turn on for a couple of seconds, when you turn the key to on? If not sure, have the pressure checked on a gauge. If throttle body injection, pressure should be about 15-20 psi. If multi-port injection (1 injector at each cylinder) the fuel pressure should be much higher-about 40-45 psi. Mazda would have a specific pressure requirement, I don't know what it is for your particular car and engine.
If the pump is working and you do have fuel pressure, you will need to check the injector circuit.
Let me know what you find. Post back if you need help diagnosing the injector circuit. First check if your new pump is turning on.
