Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (or neutral for manual transmissions) and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion on battery terminals using a wire brush.
- Tighten the battery terminals to ensure a solid connection.
Test Battery:
- If the voltage is below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
- Reconnect the battery and attempt to start the vehicle.

3. Starter Motor Inspection and Replacement

Access Starter:
- Depending on the Tacoma model, raise the front end of the vehicle and secure it on jack stands.
Remove Starter:
- Disconnect the electrical connectors from the starter motor (note their positions).
- Remove the starter mounting bolts using a socket set.
- Carefully remove the starter from the engine.
Install New Starter:
- Position the new starter in place and secure it with the mounting bolts (torque to manufacturer's specifications).
- Reconnect the electrical connectors ensuring they are secure.

4. Final Checks

Reconnect the negative battery terminal.
Start the engine to verify the repair.
