Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the battery terminals (negative first).
- Clean any corrosion from terminals using a wire brush and a mixture of baking soda and water.
Perform a Load Test:
- Use a battery load tester to check the battery's capacity; replace if it fails.
Replace the Battery (if necessary):
- Purchase a new battery that meets OEM specifications (typically a 12V lead-acid battery).
- Install the new battery, connecting the positive terminal first, followed by the negative terminal.

3. Starter Motor Check

Remove the Starter Motor:
- Disconnect battery negative terminal if not done previously.
- Remove the wiring harness connected to the starter motor.
- Unbolt the starter motor from its mounting location.
Test the Starter Motor:
- Bench test the starter motor using jumper cables to ensure it engages properly.
- Replace the starter motor if it does not function correctly.

4. Ignition System Check

Inspect Spark Plugs and Coils:
- Remove the spark plug wires and inspect for damage.
- Check the spark plugs for wear and replace if necessary (typically every 60,000 miles).
- Test ignition coils with an ohmmeter; replace if outside specified resistance range.
