from memory..

When you turn the ignition on the fuel pump will activate and click a few times. It should then only pump when the engine is running. If it is pumping all the time you may have dodgy wiring into / around the fuel pump cut off relay.

Not much to do except sit down with the wiring diagram, volt meter, and the loom and get testing...
