Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Tools Required: Multimeter, battery terminal cleaner, wrench.
Clean the battery terminals with a battery terminal cleaner if corrosion is present.
Reconnect the terminals securely.
If the battery voltage is below 12.4 volts, proceed to jump-start or replace the battery.

3. Starter Motor Check

Tools Required: Socket set, multimeter, wrench.
Locate the starter motor, usually near the transmission.
Check for proper connections to the starter motor and solenoid.
Use a multimeter to check for voltage at the starter terminal when the ignition key is turned.
If no voltage is detected, further investigate the ignition switch or wiring.

4. Replace Battery or Starter (if needed)

If the battery fails the load test, replace it with a new battery (ensure it matches vehicle specifications).
If the starter motor is faulty, remove the starter:
- Remove any components obstructing starter access.
- Disconnect wiring from the starter.
- Unbolt the starter from its mounting.
- Install the new starter by reversing the removal steps, ensuring all connections are secure.

5. Final Checks

Reconnect the negative battery terminal.
Test the system by attempting to start the vehicle.
