Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shock.
Gather all necessary tools and parts.

2. Check Fuel Pump

Locate the fuel pump access panel (if available) or remove the rear seat to access the fuel pump.
Disconnect the electrical connector from the fuel pump.
Use a multimeter to test the fuel pump voltage while turning the ignition to the "On" position.
If voltage is present but the pump does not operate, replace the fuel pump.

3. Inspect Fuel Lines

Visually inspect the fuel lines for any cracks or leaks.
If leaks are found, replace the damaged section of the fuel line.
Ensure all connections are tight and secure.

4. Replace Fuel Filter

Locate the fuel filter, usually along the fuel line near the engine.
Place a container under the filter to catch spilled fuel.
Use wrenches to loosen the fittings and remove the old fuel filter.
Install the new fuel filter in the correct orientation and tighten the fittings securely.

5. Fuel System Prime

Reconnect the battery.
Turn the ignition to the "On" position several times without starting the engine to prime the fuel system.
Check for any leaks around the fuel filter and lines.
