Solution

1. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative terminal of the battery to ensure safety.
2. Remove the battery from the vehicle using a socket set.
3. Test the battery voltage; replace if below 12.4 volts.
4. Clean battery terminals and cable connectors with a wire brush to remove corrosion.
5. Reinstall the battery and reconnect the terminals, ensuring a tight fit.

2. Fuel System Check

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Attach a fuel pressure gauge and turn the ignition to the "ON" position (do not start) to check for proper fuel pressure.
3. If pressure is low, inspect the fuel pump and fuel filter for clogs or failures.
4. Replace the fuel filter if necessary, and consider replacing the fuel pump if it is not functioning correctly.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor and disconnect the battery again for safety.
2. Inspect the wiring and connections to the starter for damage or corrosion.
3. Test the starter motor operation by directly applying voltage if possible.
4. Replace the starter motor if it shows signs of failure.
