• Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 2.
• Remove the spark plug using a socket wrench.
• Inspect the spark plug for wear or damage; replace if necessary.
• Install a new spark plug, ensuring it is gapped correctly as per manufacturer specifications.

3. Check and Replace Ignition Coil

• Inspect the ignition coil for signs of damage or wear.
• If faulty, remove the ignition coil from cylinder 2.
• Install a new ignition coil, ensuring it is securely connected.

4. Test Fuel Injector

• Remove the fuel injector from cylinder 2.
• Connect a fuel injector tester to verify its operation.
