Solution

1. Preparation

Tools Required: Multimeter, socket set, wire brush or battery terminal cleaner, safety gloves, safety goggles.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-steps:
1. Reconnect the multimeter to the battery terminals.
2. If voltage is below 12.6 volts, charge or replace the battery.
3. Clean the battery terminals with a wire brush to remove corrosion.
4. Tighten battery terminals securely.

3. Starter Relay and Motor Inspection

Sub-steps:
1. Remove the starter relay from the fuse box.
2. Swap it with a similar relay to test functionality.
3. If the issue persists, proceed to the starter motor.
4. Locate the starter motor, typically near the transmission bell housing.
5. Inspect the electrical connections to the starter motor; clean and tighten as necessary.

4. Starter Replacement (if necessary)

Sub-steps:
1. Remove the bolts securing the starter motor using a socket set.
2. Disconnect the electrical connectors from the starter.
3. Install the new starter motor by reversing the removal process.
4. Torque the starter bolts to the manufacturer’s specifications (typically around 36 ft-lbs but check the manual).
5. Reconnect the battery terminals.
