- Tools: Fuel pressure gauge, socket set, screwdrivers
- Sub-steps:
  1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
  2. Disconnect the negative battery terminal.
  3. Lift the rear seat or access panel to reach the fuel pump assembly.
  4. Disconnect fuel lines from the pump, taking care to avoid fuel spillage.
  5. Remove the fuel pump assembly and replace the fuel filter if applicable.
  6. Install the new fuel pump and reconnect all lines securely.

3. Inspecting the Air Intake System

Air Filter Replacement
- Tools: Screwdrivers, socket set
- Sub-steps:
  1. Locate and remove the air intake cover.
  2. Lift out the old air filter and inspect for dirt and debris.
  3. Insert a new air filter that meets manufacturer specifications.
  4. Reattach the intake cover securely.

4. Checking the Ignition System

Spark Plug Replacement
- Tools: Spark plug socket, torque wrench
- Sub-steps:
  1. Remove the ignition coil by unscrewing it from the engine.
