Okay, sorry... I looked back over what you're doing and see what you're doing... powering +B and +1B from the BATT line. IMO it would be better to bypass the relay directly than to introduce power from a line which is already running all over the place (noise) and may be suspect itself.
Oh, and the circuit opening relay which powers the fuel pump is switched by the main EFI relay AND the ECU has an emergency shutoff should it believe there is no air flow... so ECU and main EFI relay are both possibilities for no power to the fuel pump. The relay is more likely unless you've had a blown heater core steam the innards of the ECU.
