Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (for automatic) or neutral (for manual).
Disconnect the battery to ensure safety during repairs.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Remove any corrosion using a wire brush.
- Ensure terminals are tight and secure.
Battery Testing:
- Use a multimeter to check the voltage:
  - If voltage is below 12.4 volts, consider replacing the battery.
Replace Battery if Necessary:
- Remove the negative terminal first, followed by the positive terminal.
- Unscrew the battery hold-down clamp and lift out the old battery.
- Place the new battery in the tray and secure with the clamp.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Inspection and Replacement

Check Starter Functionality:
- If the battery is fine, locate the starter motor.
- Use a jumper wire to bypass the starter solenoid:
  - Connect one end of the wire to the positive terminal of the battery and the other end to the starter terminal.
Replace Starter if Necessary:
- Disconnect battery again if previously connected.
- Remove electrical connections from the starter (positive terminal and solenoid wire).
- Unbolt the starter from its mounting location (usually two to three bolts).
- Install the new starter in reverse order, ensuring all connections are secure.
