Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, basic hand tools.
Disconnect the battery to prevent electrical shorts.

2. Addressing Fuel Delivery Issues

a. Fuel Pump Replacement (if required)

Remove the rear seat or access panel to reach the fuel pump.
Disconnect the fuel lines, making sure to relieve fuel pressure first.
Unscrew the pump assembly and replace it with a new unit.
Reconnect the fuel lines and ensure they are secure.

b. Fuel Filter Replacement (if clogged)

Locate the fuel filter along the fuel line.
Use a wrench to disconnect the inlet and outlet hoses.
Replace with a new fuel filter, ensuring correct flow direction.

3. Cleaning or Replacing Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
If damaged, replace the throttle body with a new one.

4. Spark Plug and Ignition Coil Check

Remove the ignition coils and spark plugs using a socket set.
Inspect for wear; replace if necessary with OEM parts.
Reinstall the components ensuring proper torque specifications (typically around 15 lb-ft for spark plugs).
