Solution

1. Battery Inspection and Maintenance

Sub-steps:
- Disconnect the negative terminal of the battery.
- Clean the battery terminals using a wire brush and a mixture of baking soda and water.
- Reconnect the battery terminals securely, starting with the positive terminal.
Tools Required: Wire brush, baking soda, wrench set.

2. Battery Replacement (if necessary)

Sub-steps:
- If the battery voltage is below 12.4 volts or the battery is older than 3-5 years, remove the battery by unbolting the hold-down clamp.
- Disconnect the positive terminal first, followed by the negative terminal.
- Install a new battery, connecting the negative terminal first and securing it with the clamp.
Tools Required: Wrench set.

3. Starter Motor Check

Sub-steps:
- Check the starter motor terminals for corrosion and clean if necessary.
- Test the starter motor by connecting it directly to the battery to see if it engages.
- Replace the starter motor if it fails to engage.
Tools Required: Multimeter, wrench set.

4. Fuel System Check

Sub-steps:
- Inspect the fuel lines for leaks or blockages.
- Check the fuel pump operation by listening for a humming sound when the ignition is turned on.
- Replace the fuel filter if it is clogged.
Tools Required: Fuel pressure gauge (if needed), wrench set.
