Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery cable to prevent electrical shorts.

2. Battery Inspection

Tools Required: Multimeter
Check battery voltage again; if under 12.4 volts, proceed to jump-start.
If jump-starting works, replace the battery if it fails to hold a charge after testing.

3. Starter Relay Inspection

Tools Required: None (hands and a flathead screwdriver)
Remove the fuse box cover.
Swap the starter relay with another relay of the same type.
Attempt to start the vehicle again.

4. Starter Motor Replacement (if needed)

Tools Required: Socket set, torque wrench, ratchet
Locate the starter motor under the vehicle (usually near the transmission).
Disconnect the battery negative cable again for safety.
Remove the electrical connectors from the starter motor.
Unbolt the starter motor from its mounting bracket (usually 2-3 bolts).
Replace with a new starter motor, ensuring correct alignment.
Torque the mounting bolts to the manufacturer’s specifications (typically around 15-25 ft-lbs).
Reconnect the electrical connectors.
