Check the fuel filter:
1. Locate the fuel filter: The fuel filter is typically located in the engine compartment, along the fuel line. It is usually a cylindrical-shaped component with two fuel lines connected to it.
2. Inspect the fuel filter: Check the fuel filter for any visible signs of damage, such as cracks, leaks, or excessive dirt and debris. If the filter is clogged or dirty, it can restrict fuel flow and cause the engine to run lean.
3. Replace the fuel filter: If necessary, replace the fuel filter with a new one. Make sure to use the correct type of filter specified for your vehicle.
Check the fuel pump:
1. Listen for the fuel pump: Turn the ignition key to the "ON" position but do not start the engine. You should hear a buzzing sound coming from the fuel pump. This indicates that the pump is functioning properly.
2. Check fuel pressure: Connect a fuel pressure gauge to the fuel line and check the fuel pressure. The fuel pressure should be within the manufacturer's specified range. If the pressure is too low, the fuel pump may be faulty or there could be a problem with the fuel line.
By following these steps and performing the necessary checks, you can determine whether the problem lies with the fuel pump or the fuel filter and take the appropriate steps to address the issue.
