Solution

1. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative terminal of the battery to ensure safety.
2. Clean any corrosion from the battery terminals and cable connections using a wire brush.
3. Test the battery with a load tester; if the voltage drops below 9.6 volts under load, replace the battery.
4. Install a new battery, ensuring proper terminal connection and secure mounting.

2. Starter Motor Check

Sub-steps:
1. Reconnect the battery and test the starter by attempting to start the engine.
2. If the starter fails, remove it by disconnecting electrical connections and unbolting it from the engine block.
3. Inspect the starter for any visible damage or wear; replace if necessary.

3. Fuel System Inspection

Sub-steps:
1. Check fuel injector operation by removing the fuel rail and visually inspecting for leaks or clogs.
2. Replace any faulty fuel injectors with quality OEM parts.
3. Ensure the fuel filter is clean and replace it if clogged.

4. Spark Plug Replacement

Sub-steps:
1. Remove the ignition coils to access the spark plugs.
2. Inspect each spark plug for wear; replace plugs that are fouled or worn with new ones (using the manufacturer-specified gap).
3. Reinstall the ignition coils ensuring proper torque specifications are followed.
