How do you diagnose a Peugeot 206 fuel pump?

To diagnose a fuel pump issue in a Peugeot 206, start by checking for fuel delivery at the fuel rail. Listen for the pump's operational noise when the ignition is turned on; if it's silent, the pump may be faulty. Additionally, inspect the fuel pump relay and fuse for any defects. If necessary, use a multimeter to test the pump's electrical connections and ensure proper voltage is reaching the pump.
