Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Inspect the Battery:
- Check for any signs of corrosion on battery terminals.
- Clean terminals with a wire brush and a mixture of baking soda and water if corrosion is present.
Replace the Battery (if necessary):
1. Remove the battery retaining bracket using a socket set.
2. Disconnect the positive terminal first, then the negative terminal.
3. Remove the old battery and replace it with a new one.
4. Connect the new battery, attaching the positive terminal first, followed by the negative terminal.
5. Reinstall the battery retaining bracket and tighten to specifications.

3. Starter Inspection and Replacement

Inspect the Starter:
1. Locate the starter motor, typically found near the transmission.
2. Disconnect the wiring harness from the starter.
3. Remove the mounting bolts using a socket set and carefully take out the starter motor.
Replace the Starter (if necessary):
1. Install the new starter motor by aligning it with the mounting holes.
2. Secure with mounting bolts, torqueing to manufacturer specifications (typically around 15-20 lb-ft).
3. Reconnect the wiring harness to the starter motor.

4. System Check

Reconnect the negative battery terminal.
Check all connections and ensure they are secure.
Attempt to start the vehicle to verify that the issue has been resolved.
