Solution

1. Preparation

Gather necessary tools and parts. Disconnect the battery to ensure safety while working on electrical components.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge.
Parts Required: Ignition coil, spark plugs, fuses (if needed).

2. Replace Ignition Coil

Locate the Ignition Coil: Open the hood and identify the ignition coil(s) located on top of the engine.
Remove Electrical Connector: Carefully disconnect the electrical connector from the ignition coil.
Unbolt the Ignition Coil: Use a socket set to remove the bolts securing the ignition coil to the engine.
Install New Ignition Coil: Position the new ignition coil in place and secure it with bolts. Torque to manufacturer specifications.
Reconnect Electrical Connector: Reattach the electrical connector to the new ignition coil.

3. Replace Spark Plugs

Remove Spark Plug Wires: Carefully detach the spark plug wires, noting their order for reinstallation.
Extract Old Spark Plugs: Use a socket set to remove the old spark plugs from the engine.
Install New Spark Plugs: Insert new spark plugs and torque them to the manufacturer’s specifications.
Reconnect Spark Plug Wires: Reattach the spark plug wires to their respective plugs.

4. Check and Replace Fuses

Locate Fuse Box: Find the fuse box, typically located under the dashboard or in the engine compartment.
Inspect Fuses: Check for any blown fuses related to the ignition system. Replace as necessary.
Reassemble Fuse Box: Ensure all fuses are properly seated and close the fuse box cover.

5. Verify Fuel Supply

Check Fuel Pump Operation: Turn the ignition to the "ON" position (do not start) and listen for the fuel pump priming sound.
Test Fuel Pressure: Use a fuel pressure gauge to check if the fuel pressure is within the manufacturer's specifications. If low, investigate fuel filter and pump.
Reconnect Battery: After all repairs are completed, reconnect the battery.
