Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, engine oil, coolant.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shock during repairs.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and document any trouble codes present.
Use manufacturer resources to interpret the codes related to the blinking engine light.

3. Inspect and Replace Spark Plugs

Remove the ignition coil connectors and unscrew the ignition coils.
Use a socket wrench to remove spark plugs.
Inspect spark plugs for signs of wear; replace if necessary (use OEM specifications).
Reinstall new spark plugs, ensuring the correct torque (typically 13-16 lb-ft).

4. Check and Replace Ignition Coils

Test ignition coils for proper resistance using a multimeter (check OEM specifications).
If any coils are faulty, remove and replace with new ignition coils.
Reconnect ignition coils and connectors securely.

5. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Start the engine and monitor fuel pressure; ensure it meets manufacturer specifications.
If the pressure is low, inspect the fuel pump and fuel filter for blockages or failures.
Replace the fuel pump or filter as needed.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any trouble codes.
Start the engine and check if the engine warning light remains off.
