take a look at the wiring schematic at the following link --

specifically, note how the dme relay completes the circuit between pin 30 "+12 volt from battery unfused" and pin 87b "+12 volt to fuel pump via fuse 3"

this suggests to me that the f9 IS the source of your always running fuel pump, as the same result would occur if you simply inserted a jumper wire between pins 30 and 87b
