When you first turn the ignition switch to the "on" position the fuel pump relay should pull in and the fuel pump should run (for a while). With the engine not running the fuel pump will shut off after a short period of time.

I don't know enough about Holley's fuel pumps, but as a general statement, electric fuel pumps appear to often use the flow of fluid through the pump to cool the pumps.

Something you might try... disconnect the fuel pump wiring (connector at the fuel pump). Hook up a volt meter. Switch on the iginition. Are you seeing +12 volts at the connector end? If so, you know you are getting power to the pump. If no power, check the fuel pump relay or the hot wire from the fuse box to the fuel pump relay (I seem to remember that there is a separate power wire going to the fuel pump relay ... makes it easier to insert an inertia kill switch).
