To be certain:
1. Consult your owner's manual: This is the best resource for the exact location in your specific vehicle. The manual will have a diagram of the fuse box with all the relays identified.
2. Look for the fuse box: This is usually located under the hood, often near the battery. It's a plastic box with numerous fuses and relays.
3. Look for a diagram inside the fuse box cover: The cover itself frequently has a diagram showing the location of fuses and relays. The fuel pump relay may be labeled "Fuel Pump" or something similar, or it might be indicated by a symbol (often a gas pump icon).
4. If you can't find it in the under-hood fuse box: It's *extremely unlikely* to be elsewhere, but in rare cases, some older Fords might have it in the interior fuse box (usually located in the dashboard), but this is less common for the 2000 Focus.
If you're still unable to locate it after checking these areas, consider consulting a Ford mechanic or an online forum dedicated to Ford Focus owners. Providing your Focus's engine size (e.g., 2.0L Zetec) might help forum members give you more precise guidance.
