* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. The relay itself might be labeled, or you might need to consult your owner's manual or a wiring diagram to identify it.
* Inside the car's cabin, typically near the fuse box under the dashboard: Less common, but possible.
To find it, you should:
1. Consult your owner's manual: This is the best place to start. The manual will have a diagram showing the location of all fuses and relays.
2. Look in the fuse box under the hood: Carefully examine all the relays. Some might be labeled, others might not. If you can't find it visually, you may need to use a multimeter to test relays individually to find the one controlling the fuel pump. (A wiring diagram helps here).
3. Check the fuse box inside the car (if applicable): If you can't find it under the hood, check for a secondary fuse box inside the cabin.
Important Note: Working with automotive electrical systems can be dangerous. If you're not comfortable doing this, it's best to take your car to a qualified mechanic. Incorrectly handling relays or fuses can damage your vehicle's electrical system.
