my Skoda Octavia NFL (2020-Present) has a hard start issue in the morning

Solution

1. Preparation

• Gather tools and parts required for repairs.
• Ensure the vehicle is parked on a level surface and the ignition is turned off.
• Disconnect the battery to prevent electrical shock.

2. Battery Inspection and Replacement

• Sub-steps:
  1. Remove the battery cables, starting with the negative terminal.
  2. Inspect the battery for any signs of swelling or leaks; replace if necessary.
  3. Clean the battery terminals and cable ends with a wire brush.
  4. Reconnect the battery, first the positive terminal, then the negative.

Tools Required:

• Wrench set
• Wire brush
• Multimeter

3. Fuel System Check

• Sub-steps:
  1. Locate the fuel pressure test port on the fuel rail.
  2. Connect the fuel pressure gauge to the test port.
  3. Turn the ignition to the "ON" position (do not start) to check for fuel pressure.
  4. If the pressure is below specifications (typically around 50-60 psi for most vehicles), replace the fuel pump.
  5. Disconnect the fuel gauge and reattach the test port cap.

Tools Required:

• Fuel pressure gauge
• Wrench set

4. Ignition System Check

• Sub-steps:
  1. Remove the spark plug wires or coils (as applicable).
  2. Inspect the spark plugs for signs of wear or fouling; replace if necessary.
  3. If spark plugs are okay, check the ignition coils with a multimeter for proper resistance.
  4. Reinstall spark plugs and wires or coils.

Tools Required:

• Socket set
• Torque wrench
