Solution

1. Preparation

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

2. Battery Inspection

Inspect the battery for any signs of damage or corrosion.
Clean the battery terminals with a wire brush and a mixture of baking soda and water.
Reconnect the battery terminals tightly.

3. Starter Relay Replacement

Locate the starter relay in the fuse box.
Remove the relay using a relay puller or flathead screwdriver.
Replace with a new starter relay ensuring it is the correct part number.

4. Starter Motor Testing

Access the starter motor by removing any covering or components blocking access.
Use a multimeter to check for voltage at the starter motor's positive terminal.
- If no voltage, trace wiring back to the ignition switch.
Test the starter motor by applying direct power from the battery to the starter terminal.
- If it engages, the starter motor is functional; replace wiring or ignition switch if it does not.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Attempt to start the vehicle and observe any changes.
