Solution

1. Preparation

Gather tools: multimeter, socket set, torque wrench, battery terminal cleaner, load tester.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect the negative battery terminal using a socket set.
Clean the battery terminals and connectors using a battery terminal cleaner.
Reconnect the terminals and ensure they are tight.
If the battery voltage is low (below 12.4 volts), replace the battery with a new one of the same specifications.

3. Starter Relay and Fuses

Locate the fuse box in the engine compartment.
Remove the starter relay and visually inspect for damage.
Swap the starter relay with a similar relay to test functionality.
Check the fuses related to starting; replace any that are blown.

4. Starter Motor Inspection

If the issue persists, locate the starter motor.
Disconnect the wiring harness from the starter.
Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
If voltage is present but the starter doesn't engage, remove the starter motor:
- Unscrew the mounting bolts and remove the starter.
- Inspect the starter for any signs of wear or damage.
Replace the starter motor if it is faulty.

5. Reassemble

Reinstall the starter motor and secure it with the mounting bolts; torque them to manufacturer specifications.
Reconnect the wiring harness to the starter.
Reconnect the negative battery terminal.
Start the vehicle to test.
