To find it, you'll need to:
1. Consult your owner's manual: This is the best place to start. The manual will have a fuse and relay diagram specific to your vehicle.
2. Check the fuse box diagrams: There are usually diagrams on the inside of the fuse box covers (both the under-hood and interior fuse boxes). Look for a diagram showing the relays and their associated functions. The fuel pump relay is often labeled or depicted near the fuel pump symbol.
3. Common locations: The relay is typically found in either the under-hood fuse box (often located near the battery) or an interior fuse box (usually under the dashboard).
4. If you can't find it in the diagrams: Search online forums specific to your year and model of Rover 400. Many owners have documented their experiences and may have pictures of the relay's location. Be sure to specify the engine size (e.g., 1.6, 1.8, 2.0 liter) when searching.
Without knowing the specific year and engine of your Rover 400, it's impossible to give a precise location. Using the steps above will greatly increase your chances of finding it quickly.
