The EDIC motor grounds to the engine, and your engine ground strap will go to the frame. I do not recall if the Fuel Relay grounds to the glovebox, or if Toyota has included it in their ground loop. Download the manual from Birfield and check the wiring diagrams...
Ground the EDIC motor to the frame with some cables, and see if that eliminates it. Lowenbrau mentioned either this, or something else he has grounded...during the process of elimination...
