Solution

1. Preparation

Gather tools: multimeter, socket set, torque wrench, battery terminal cleaner, and safety glasses.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Clean the battery terminals using a terminal cleaner or a wire brush.
Tighten the battery terminals to ensure a secure connection (typically 10-15 ft-lbs of torque).

3. Battery Replacement (if needed)

If the battery voltage is below 12.4 volts or fails to hold a charge, remove the old battery:
1. Disconnect the positive terminal, then the negative terminal.
2. Remove any hold-down brackets securing the battery.
3. Lift the battery out of the battery tray.
Install the new battery:
1. Place the new battery in the tray.
2. Reattach the hold-down brackets.
3. Connect the positive terminal, then the negative terminal.

4. Starter and Relay Check

If the battery is functional but the problem persists, inspect the starter and relay:
1. Locate the starter motor and its connections; ensure all wiring is intact and connected.
2. If necessary, remove the starter for bench testing or replacement:
  - Disconnect wiring from the starter.
  - Remove mounting bolts and take the starter out.
  - Test the starter by connecting it directly to a power source.
3. Replace the starter if it fails to engage.

5. Reassemble and Test

Reconnect the negative battery terminal.
Attempt to start the vehicle to verify the repair.
