Solution

1. Preparation

Gather tools: Multimeter, socket set, jumper cables, torque wrench, and screwdriver.
Ensure the vehicle is in park or neutral, and the parking brake is engaged.
Disconnect the battery negative terminal to prevent accidental short circuits.

2. Battery Inspection

a. Clean Terminals: Remove corrosion from battery terminals using a wire brush and a mixture of baking soda and water.
b. Tighten Connections: Ensure all connections are secure and tight.
c. Replace Battery (if needed): If the battery voltage is low (below 12.4 volts), replace it with a new, fully charged battery. Torque the terminals to the manufacturer's specifications (typically around 10-15 ft-lbs).

3. Starter Relay and Fuse Check

a. Swap Relay: Remove the starter relay and swap it with an identical relay in the fuse box.
b. Inspect Fuses: Check the fuses associated with the starting system. Replace any blown fuses with the appropriate amperage.

4. Starter Motor Inspection

a. Locate Starter: Access the starter motor, typically located on the engine block near the transmission.
b. Inspect Wiring: Check the wiring harness and connections to the starter for any signs of damage or loose connections.
c. Test Starter Motor: If the starter appears intact, apply direct power from the battery to the starter terminal to see if it engages.

5. Reassemble and Test

Reconnect the battery negative terminal.
Start the vehicle to check if the problem is resolved.
