Solution
1. Preparation
  • Tools Required: Socket set, OBD-II scanner, multimeter, fuel pressure gauge, screwdriver set.
  • Disconnect the negative battery terminal to prevent electrical shock.
  • Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
2. Remove Fuel Pump

  1. Access the Fuel Pump:

    • Raise the vehicle using a jack and secure it on jack stands.
    • Remove the fuel tank or access panel (if applicable) to reach the fuel pump assembly.

  2. Disconnect Fuel Lines:

    • Use appropriate tools to disconnect the fuel lines from the fuel pump.
    • Be prepared for some fuel spillage; have rags or a container ready.
