Subject: '03 Taurus 3.0 fuel pump won't quit

We're testing an '03 Taurus w/ 3.0 pushrod motor,125k, Fuel pump runs continuously w/ key on, engine off. It is supposed to shut off after a second or two. I checked the relays, (PCM and fuel pump) oil switch checks ok, replaced the fuel pump driver module, still the same............ Any ideas? Does the fuel pressure sender on the fuel rail have to reach pressure to cut the pump off? The Ford manual is NOT clear about any of this system.
