my Skoda Octavia NFL (2020-Present) turns over but won't start

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the battery to ensure safety during repairs.

2. Check Fuel System

• Sub-step 1: Reconnect the battery.
• Sub-step 2: Use a fuel pressure gauge to connect to the fuel rail.
• Sub-step 3: Turn the ignition to the "ON" position (do not start) and check for proper fuel pressure (typically around 50-60 psi for most vehicles).
• Sub-step 4: If pressure is low, inspect the fuel pump and fuel filter for blockages or failures.
• Tools Required: Fuel pressure gauge.

3. Inspect Ignition System

• Sub-step 1: Remove the spark plugs using a socket set.
• Sub-step 2: Inspect spark plugs for wear or damage; replace if necessary.
• Sub-step 3: Test ignition coils with a multimeter to ensure proper resistance (typically 0.4-2.0 ohms).
• Tools Required: Socket set, multimeter.

4. Examine Battery and Connections

• Sub-step 1: Use a multimeter to measure battery voltage (should be above 12.4 volts).
• Sub-step 2: Check for corrosion and secure connections at the battery terminals and ground points.
• Sub-step 3: Clean any corrosion using a wire brush and reconnect securely.
• Tools Required: Multimeter, wire brush.

5. Reassemble and Test

• Sub-step 1: Reinstall spark plugs and any removed components.
• Sub-step 2: Reconnect the battery.
• Sub-step 3: Attempt to start the vehicle and observe if it starts successfully.
