my Skoda Octavia NFL (2020-Present) has a hard time starting after filling gas

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery negative terminal to prevent electrical shorts.

2. Inspect Fuel Filler Cap

• Remove the fuel filler cap and examine it for cracks or damage.
• Clean the sealing surface on the fuel filler neck.
• Replace the fuel filler cap if damaged.

3. Check Fuel Pressure

• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition to the "On" position without starting the engine to prime the fuel system.
• Check the gauge reading; it should meet manufacturer specifications (usually around 50-60 psi).
• If pressure is low, proceed to the next step.

4. Test Fuel Pump

• Reconnect the battery and turn the ignition on to activate the fuel pump.
• Listen for the fuel pump operation; it should sound like a brief whirring noise.
• If no sound is heard, inspect the fuel pump relay and fuse.
• If the pump is faulty, replace it following the steps below.

5. Replace Fuel Pump (if necessary)

• Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
• Disconnect the battery again.
• Remove the rear seat (if applicable) to access the fuel pump module.
• Disconnect the electrical connector and fuel lines from the pump.
• Unscrew the retaining ring and carefully remove the fuel pump assembly.
• Replace with a new fuel pump and reverse the removal procedure.
