You'll need to consult your owner's manual or a wiring diagram specific to your 2000 Ford Taurus to pinpoint the exact location of the fuel pump relay within the PDB. The diagram will show the relay's position and possibly even its number. The relay itself might be labeled, but often isn't.
Without a diagram, searching visually in the PDB can be time-consuming and potentially frustrating. A simple search online for "2000 Ford Taurus fuel pump relay location diagram" will likely yield helpful results.
