hi, did you check voltage and ground at fuel pump connector, before changing anything? For the pump motor, gray wire is voltage and black is ground. Check ecm B fuse, if no voltage. There should be a fuel pump test connector, under the hood, driver-side rear. A red wire with electrical connector, nothing plugged into it. If you use a jumper wire with inline fuse between battery and connector, the pump should run, don't need to use the key.
