my Skoda Octavia NFL (2020-Present) stalls after filling up, what might be the issue?

Solution

1. Preparation

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

2. Inspect Fuel Filler Neck and Cap

• Remove the fuel cap and visually inspect for cracks or damage.
• Replace the fuel cap if necessary (ensure it is the correct part for the Octavia NFL).
• Check the fuel filler neck for any signs of corrosion or blockage.

3. Test Fuel Pump Operation

• Locate the fuel pressure test port on the fuel rail.
• Attach a fuel pressure gauge and turn the ignition to the "ON" position (do not start the engine).
• Check the fuel pressure; it should match specifications (typically around 50-60 psi).
• If pressure is low, consider replacing the fuel pump.

4. Inspect EVAP System

• Locate the charcoal canister and inspect for cracks or damage.
• Check the hoses connected to the EVAP system for blockages or leaks.
• If the canister is damaged, replace it with a new one.

5. Clean or Replace Fuel Injectors

• Remove the fuel injectors using a socket set.
• Clean the injectors using a cleaning kit or replace them if clogged.
• Reinstall the injectors ensuring they are seated properly.

6. Reassemble and Test

• Reconnect the battery and fuel cap.
• Start the engine and monitor for any abnormal sounds or behaviors.
• Test drive the vehicle to ensure the stalling issue is resolved.
