Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Fuel Filter

• Locate the fuel filter (usually along the fuel line).
• Using a socket set, remove the fuel lines from the filter carefully.
• Replace the old filter with a new one, ensuring the flow direction is correct.
• Reconnect the fuel lines securely and check for leaks.

3. Clean or Replace Fuel Injectors

• Remove the intake manifold if necessary to access the fuel injectors.
• Use a fuel injector cleaning kit to clean the injectors or replace them if they are clogged or damaged.
• Reinstall the intake manifold and ensure all connections are secure.

4. Check and Replace Fuel Pump (if necessary)

• Access the fuel pump, typically located in the fuel tank.
• Disconnect the electrical connector and fuel lines.
• Remove the pump assembly and inspect it for damage.
• Replace with a new pump if malfunctioning, following the manufacturer's instructions for installation.
