Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is in a safe area, and set the parking brake.
Disconnect the negative battery terminal to prevent any electrical shock.

2. Inspect and Clean Battery Connections

Tools Required: Wrench set, wire brush or battery terminal cleaner.
Check the battery terminals for corrosion; if present, clean them using the wire brush.
Tighten the connections to ensure a solid contact.

3. Test and Replace the Battery (if needed)

Tools Required: Multimeter, battery tester, socket set.
Connect the multimeter to the battery terminals; if voltage is below 12.4 volts, the battery may need charging or replacement.
If a replacement is needed, remove the old battery by loosening the hold-down bracket and disconnecting the terminals (negative first, then positive).
Install the new battery by connecting the positive terminal first, followed by the negative terminal, and secure the hold-down bracket.

4. Inspect the Starter Motor

Tools Required: Socket set, test light.
Locate the starter motor and check the wiring for any damage.
Use a test light to check for power at the starter terminal while someone turns the ignition key. If no power is present, further investigate the ignition switch and wiring.

5. Replace Faulty Components

If the starter motor or battery tests as faulty, replace with new components. For the starter, follow the manufacturer's specifications for torque values when installing.
