Disconnect the negative battery terminal to prevent electrical shorts.

2. Fuel Pump Inspection and Replacement (if necessary)

Access the Fuel Pump:
- Remove the rear seats or access panel to reach the fuel pump.
- Disconnect any electrical connectors and fuel lines carefully.
Remove Fuel Pump Assembly:
- Unbolt the fuel pump assembly using a socket set.
- Lift the fuel pump assembly out of the fuel tank.
Inspect the Pump:
- Check the condition of the pump and filter. If the pump is faulty or not functioning, replace it.

- Ensure all connections are secure and free of leaks.

3. Fuel Filter Replacement (if clogged)

Locate the Fuel Filter:
- Identify the location of the fuel filter, typically along the fuel line.
Remove the Filter:
- Depressurize the fuel system by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect fuel lines from the filter using a line removal tool.
Install New Filter:
- Install the new fuel filter in the correct orientation.
