Here are the step-by-step instructions on how to locate the fuel pump relay:
1. Open the hood of your Mercedes-Benz.
2. Locate the fuse box. It is a black plastic box located on the driver's side of the engine compartment, near the firewall.
3. Remove the cover of the fuse box.
4. Find the fuel pump relay. It is labeled "FP" or "Fuel Pump."
5. The fuel pump relay is usually a small, black relay with four terminals.
6. Once you have found the fuel pump relay, you can remove it by gently pulling it out of its socket.
Additional Notes
- The fuel pump relay is a critical part of the fuel injection system. It supplies power to the fuel pump, which is responsible for delivering fuel to the engine.
- If the fuel pump relay fails, the fuel pump will not be able to operate, and the engine will not be able to run.
- If you are experiencing problems with your fuel system, the fuel pump relay may be the cause. You can test the relay by swapping it with another relay of the same type.
