Solution

1. Preparation

Tools Required: Battery charger, multimeter, OBD-II scanner, fuel pressure gauge, socket set.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Battery Replacement

Sub-steps:
1. Remove the positive terminal first, followed by the negative terminal.
2. Unfasten the battery hold-down clamp using a socket set.
3. Carefully lift the battery out of the tray (keep it upright).
4. Install the new battery by placing it in the tray, securing it with the hold-down clamp, and reconnecting the terminals (negative first, then positive).

3. Fuel System Inspection

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail service port.
2. Turn the ignition to the 'ON' position (without cranking) and check the pressure reading; it should be within manufacturer specifications (typically 30-65 psi).
3. If pressure is low, inspect the fuel pump and filter for blockages or failures.

4. Spark Plug Replacement

Sub-steps:
1. Remove the ignition coil or plug wire from the spark plug.
2. Use a socket wrench to remove the spark plug from the cylinder head.
3. Inspect the old spark plug for damage and replace with a new spark plug if necessary, ensuring correct gap settings.
4. Reinstall the ignition coil or plug wire securely.
