Hi Willy

The pump is earth switched.

Grey to Brown/Yellow should be 12V when the pump is running
Grey to earth (or ground) should be 12V all the time the ignition is turned on

With the pump disconnected the gray wire should be battery voltage, brown/yellow is the earth feed from the ECM, black is chassis ground and yellow/red is low fuel.
