Its been a while since I played with this wiring but I do believe that the fuel pump relays have a +12v lead to the battery that is hot at all times. Doesn't mean they are passing current at all times. There is also a switched 12v to the relays that closes the main contacts and sends power to the pumps when the key is in the run and start positions.

Every 930 will eventually need some variation of this fuel pump wiring mod.
