my Skoda Octavia won't start after filling gas what's wrong

Solution

1. Preparation

• Gather tools: OBD-II scanner, fuel pressure gauge, socket set, screwdrivers, and safety goggles.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to prevent electrical shock during repairs.

2. Inspect the Fuel Pump

• Locate the fuel pump access panel (usually under the rear seat or trunk).
• Remove the access panel and connector to the fuel pump.
• Use the multimeter to test the fuel pump’s electrical connection for proper voltage.
• If voltage is present but the pump does not operate, replace the fuel pump.

3. Check Fuel Pressure

• Connect the fuel pressure gauge to the fuel rail’s service port.
• Turn the ignition to the "ON" position without starting the engine to check for fuel pressure reading.
• Compare the reading with the manufacturer’s specifications (usually between 35-60 psi).
• If pressure is below specification, check the fuel filter and replace if necessary.

4. Inspect Fuel Lines and Injectors

• Visually inspect all fuel lines for cracks or leaks.
• Tighten any loose connections and replace damaged lines.
• For injectors, disconnect the wiring harness and test for resistance using a multimeter. Replace any faulty injectors.

5. Reassemble and Test

• Reconnect all components and the fuel pump access panel.
• Reconnect the battery and clear any error codes from the OBD-II scanner.
• Attempt to start the vehicle.
