How do you reset fuel pump switch on 1994 ford explorer?

A 1994 Ford Explorer doesn't have a separate "fuel pump switch" in the way some vehicles might have an inertia switch. The fuel pump is controlled by the computer (PCM) and the fuel pump relay. There's no user-accessible switch to reset.

If you're having fuel delivery problems, here's what you should check instead of looking for a reset switch:

* Fuel Pump Relay: This is a common point of failure. Locate the fuel pump relay in the underhood fuse box (consult your owner's manual for the location). Swap it with another relay of the same amperage (to rule out a bad relay) or replace it.

* Fuel Pump Fuse: Check the fuse for the fuel pump in the underhood fuse box. Replace it if it's blown.

* Inertia Switch: While not strictly a "fuel pump switch," some Ford Explorers (though less likely in a '94) have an inertia switch that cuts power to the fuel pump in a collision. This is usually a small, button-like switch, often located under the dashboard or in the engine compartment. Check your owner's manual for its location. If found, press the button to reset it.

* Low Fuel Level: Ensure you have enough fuel in the tank. The fuel pump may not engage if the level is extremely low.

* Fuel Pump itself: If the relay, fuse, and inertia switch are all fine, the problem may be the fuel pump itself. This is a more involved repair usually requiring access to the fuel tank.

In short: There's no reset switch for the fuel pump. Troubleshooting should focus on the relay, fuse, and inertia switch (if equipped). If none of these solve the issue, you'll likely need professional help to diagnose a potential fuel pump or wiring problem.
