* Under the hood in the Power Distribution Box (PDB): This is the most common location. The PDB is usually a large black box located near the battery. The relay itself is often labeled, but you might need to consult your owner's manual or a wiring diagram to identify the correct one.
* Inside the passenger compartment fuse box: Less common, but possible. This fuse box is typically located under the dashboard on the driver's side. Again, a wiring diagram or owner's manual will be essential for pinpointing the fuel pump relay.
To find it, I strongly recommend:
1. Consult your owner's manual: This is the best resource for the exact location.
2. Use a wiring diagram: A wiring diagram specific to your vehicle's year, make, model, and engine will show you exactly where the relay is and what it looks like. You can find these online (some sites charge a fee) or at an auto parts store.
Without a diagram or manual, visually inspecting both fuse boxes is your next best bet. Look for a relay that is similar in size and shape to other relays in the boxes, and if possible, one that is labeled or near a component related to the fuel system. Be cautious when working with electrical components and disconnect the negative battery terminal before working on any relays or fuses.
