* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. Check the diagram on the inside of the fuse box lid. The relay itself may be labeled, or the diagram will show the location of the fuel pump relay.
* In the passenger compartment fuse box (under the dash): Less common, but possible. Again, consult the fuse box diagram.
To find it definitively:
1. Consult your owner's manual: This is the best source of information for your specific vehicle. The manual will have a diagram of the fuse and relay boxes.
2. Use a wiring diagram: A wiring diagram for your specific year and engine will clearly show the relay's location. You can find these online (through a subscription service like AllDataDIY or Mitchell1) or at a parts store (sometimes for free).
3. Look for a relay that's clearly labeled: Even without a diagram, some relays might have markings indicating their function (though this isn't always the case).
4. Use a multimeter: If you're comfortable working with electricity, you can use a multimeter to test relays in the fuse boxes until you find one that controls the fuel pump circuit. Caution: Disconnect the battery negative terminal before doing this.
Remember to always disconnect the negative battery terminal before working on electrical components in your vehicle.
