Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection

Inspect Battery Terminals
- Remove any corrosion using a wire brush.
- Tighten any loose connections.
Test Battery
- If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery.

3. Starter Relay Check

Locate the Starter Relay
- Access the fuse box under the hood.
Swap Relay
- Remove the starter relay and replace it with a similar relay from the fuse box.

4. Starter and Wiring Inspection

Access the Starter Motor
- Lift the vehicle and secure with jack stands.
- Remove any covers to access the starter.
