Where is the fuel pump reset button located on a 1994 Ford Thunderbird?

The reset button is inside the trunk on the driver's side. You will need to pull off some of the carpeting (Don't worry, it has velcro). You will see the module there on the side. If you want to relieve fuel pressure (like when you replace the fuel filter), unplug the electrical connector from the inertia switch. Then start the engine and run it until it stops. Once you're done working simply plug the connector back into the inertia switch. REMEMBER TO ALWAYS DISCONNECT THE NEGATIVE BATTERY CABLE BEFORE WORKING ON THE CAR. Hope this helps.
