Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect the Battery
- Clean any corrosion from the terminals using a wire brush and a solution of baking soda and water.
- If the battery voltage is below 12.4 volts, proceed to replace the battery.
Replace the Battery
- Remove the negative terminal first, followed by the positive terminal.
- Remove any holding brackets and lift the battery out of the tray.
- Place the new battery in the tray and secure it with brackets.
- Connect the positive terminal first, followed by the negative terminal.
- Ensure all connections are tight.

3. Starter Relay and Fuse Check

Inspect/Replace the Starter Relay
- Locate the under-hood fuse box and identify the starter relay.
- Swap the starter relay with a similar relay in the fuse box.
- Test to see if the vehicle starts.
Check and Replace the Starter Fuse
- Locate the fuse for the starter circuit in the fuse box.
- Remove the fuse and check for continuity. Replace if blown.

4. Starter and Wiring Inspection

Inspect Starter Connections
- Locate the starter motor underneath the vehicle.
- Check for tightness of the electrical connections on the starter.
- If connections are loose, tighten them.
Test Starter Operation
- Connect a multimeter to the starter terminals.
- Have an assistant turn the key to the "Start" position while monitoring voltage.
- If no voltage is detected, the starter may need replacement.

5. Reassemble and Test

Reassemble any components removed during inspection.
Reconnect the negative battery terminal.
Start the vehicle to check if the issue is resolved.
