To find it, you'll need to:
1. Consult your owner's manual: This is the best place to start. The manual should have a diagram showing the location of all fuses and relays.
2. Check the underhood fuse box: This is the most common location. Look for a diagram on the inside of the fuse box cover. The diagram should identify the fuel pump relay, often labeled "Fuel Pump" or with a symbol representing a fuel pump.
3. Look for a separate relay center (under the dash): If you can't find it under the hood, there might be a separate relay center under the dashboard, often near the steering column. This is less common but possible. You might need to remove a panel or two to access it.
4. Use a wiring diagram: If you're comfortable with automotive electrical systems, a wiring diagram specific to your 1992 Buick LeSabre Limited will definitively show the relay's location and circuit. You can find these diagrams online (some are free, some require a purchase) or at an auto parts store.
Important Safety Note: Always disconnect the negative battery terminal before working with any electrical components in your car. This prevents accidental shorts and protects you from electric shock.
