Solution

1. Preparation

Gather tools and materials. Ensure the vehicle is parked on a level surface and the engine is cool.
Tools Required: OBD-II scanner, multimeter, fuel pressure gauge, socket set, torque wrench.

2. Battery Replacement (if necessary)

Sub-steps:
1. Disconnect the negative terminal first, followed by the positive terminal.
2. Remove the battery hold-down bracket and lift the battery out of the tray.
3. Install the new battery in reverse order, ensuring it is secure.
4. Connect the positive terminal first, followed by the negative terminal.

3. Fuel System Inspection

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position (do not start) to check the pressure reading. It should meet manufacturer specifications.
3. If pressure is low, inspect the fuel pump and filter for blockages or failure.

4. Spark Plug Replacement (if necessary)

Sub-steps:
1. Remove the ignition coils, then carefully extract the spark plugs using a socket.
2. Inspect the spark plugs for wear or fouling; replace if necessary.
3. Gap the new spark plugs to the manufacturer specifications and install them.
4. Reinstall the ignition coils.

5. Starter Motor Check

Sub-steps:
1. Disconnect the battery again for safety.
2. Remove the starter motor from its mounting.
3. Use a multimeter to test the starter motor for resistance; replace if it shows signs of failure.
4. Reinstall the starter motor and reconnect the battery.
