Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the battery terminals and cable ends using a wire brush.
- Test the battery with a load tester; if the voltage is low or it fails the test, replace the battery.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal, ensuring a secure fit.

3. Starter Motor Testing and Replacement

Sub-steps:
- Reconnect the battery terminals.
- Locate the starter motor and test its operation by applying direct voltage.
- If the starter does not engage, remove it by disconnecting the battery again and unscrewing the mounting bolts.
- Replace the starter motor with a new unit, ensuring all connections are tight.

4. Fuel System Check

Sub-steps:
- Check the fuel pump fuse and relay for functionality.
- If the fuel pump is not operational, replace it by removing the rear seat or access panel, disconnecting the fuel lines, and unscrewing the pump assembly.
- Install a new fuel pump, ensuring proper sealing and connection.

5. Ignition System Inspection

Sub-steps:
- Remove the spark plugs and inspect for wear or carbon buildup.
- Replace any worn spark plugs with new ones, ensuring the gap is set according to specifications.
- Test and replace ignition coils if necessary.
