Which Fuse or Relay powers the Sedan's fuel pump?

For the life of me I cannot recall which fuse or relay we pulled to de-pressurize the fuel rail when we installed the S/C. The 1zz injectors cause a CEL (too rich, bank 1) during cold starts so I'd like to go back to the stock injectors for the winter. The manual makes no mention of which fuse powers the fuel pump. Many support EFI functions but those I pulled either killed the engine immediately or had no effect at idle. I recall after pulling a fuse it continued running about 10 seconds until low on fuel pressure and stalling.

Did we actually pull a fuse? Can't remember myself.

Pull EFI and crank the engine a few times. That's what I do when I need to open the fuel system. Have a small pan ready to catch what drips out when you pull of the flexible hose, as the system will not siphon that out.

Thanks Scott!

Yes Wee, I pulled most all of the fuses and also the three relays in the under-hood box. I know pulling one of them caused the engine to starve before we installed the Blitz.
