* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. It will have a removable cover. The relay itself is often labeled, or you can consult your owner's manual or a wiring diagram to identify it. Look for a relay that's related to "fuel pump," "EFI," or "engine control."
* Under the dashboard: Less common, but possible, especially on some models. If not in the underhood fuse box, it might be located in a fuse/relay panel under the dash.
To find it, I strongly recommend:
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. Use a wiring diagram: You can find these online through sites specializing in automotive repair information (like Chilton or Haynes). These diagrams will show you exactly where the fuel pump relay is and its corresponding fuse.
3. Look for markings: Once you've opened the fuse box(es), carefully examine each relay. Some might have markings that indicate their function.
Caution: Always disconnect the negative terminal of your battery before working with any electrical components in your vehicle. This is a safety precaution to avoid electrical shock or short circuits.
