As far as I know, ignition switch is the only thing between the battery and pin 9 on the fuel pump relay. The OVP relay can also bring this pin down to a low voltage. Remove the OVP relay and see if you get battery voltage on pin 9. If you get the voltage back, it can be either a bad OVP relay or you have a voltage higher than acceptable level, i.e. a possible bad alternator or bad voltage regulator. If you dont get approx 12V after OVP relay is removed, you have a bad ignition switch or a broken cable from switch to the fuel pump relay socket.
