Solution

1. Preparation

Gather tools and materials needed: socket set, multimeter, battery terminal cleaner, wrench set, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

1.1 Disconnect the negative terminal of the battery using a wrench to prevent electrical shorts.
1.2 Clean any corrosion from the battery terminals with a battery terminal cleaner.
1.3 Reconnect the battery terminals securely, starting with the positive terminal followed by the negative terminal.

3. Starter Motor Testing

2.1 Locate the starter motor, usually near the bottom of the engine near the transmission.
2.2 Disconnect the electrical connector from the starter.
2.3 Using a jumper wire, apply 12 volts directly to the starter motor's terminal to check if it engages. If it does not, the starter may need replacement.

4. Wiring and Connections

3.1 Inspect all wiring connected to the battery and starter for any fraying, breaks, or corrosion.
3.2 Repair or replace any damaged wiring as necessary.
3.3 Ensure that all connections are tight and secure.

5. Final Checks

4.1 Reconnect the starter motor's electrical connector.
4.2 Reconnect the battery terminals and ensure they are secure.
4.3 Attempt to start the vehicle again to confirm resolution of the issue.
