The fuel pump relay location on a 1996 Ford Probe is
in the Power Distribution Box (PDB), also known as the fuse box under the hood. It's *not* always clearly labeled as "fuel pump relay". You'll likely need to consult your owner's manual or a wiring diagram to pinpoint the exact relay. The manual will show you the PDB layout and identify the relay.
Look for a relay that's associated with the fuel system or fuel injection. Often, there are several relays grouped together in the PDB, and you may have to test each one using a multimeter to determine the correct one. Always disconnect the negative battery terminal before doing any testing or work around electrical components.
