Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety.
  • Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
2. Inspect and Replace Fuse
  • Locate the fuse box in the Tiguan.
  • Identify the fuel pump fuse using the diagram on the fuse box cover.
  • Remove the fuse and check for continuity with a multimeter.
  • If the fuse is blown, replace it with one of the same amperage (typically 15A).
3. Test and Replace Fuel Pump Relay
  • Locate the fuel pump relay in the fuse box.
  • Remove the relay and test it with a multimeter for continuity.
  • If the relay is faulty, replace it with a new relay of the same specifications.
4. Check Fuel Pump Power Supply
  • Reconnect the battery and use a voltmeter to check for voltage at the fuel pump connector while turning the ignition key to the ON position (not start).
  • If there is no voltage, trace the wiring back to the relay and inspect for any breaks or shorts.
5. Replace Fuel Pump (if necessary)
  • If the pump is still not receiving power after confirming the relay and wiring are functional, remove the fuel pump assembly from the fuel tank.
  • Inspect the pump for any signs of damage and replace if necessary.
  • Reinstall the fuel pump assembly and reconnect all electrical connections securely.
