Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Clean Battery Connections

Sub-steps:
1. Remove the negative cable from the battery terminal.
2. Remove the positive cable and inspect for corrosion.
3. Clean both terminals and cable ends with a wire brush or terminal cleaner.
4. Reconnect the positive cable first, followed by the negative cable.

3. Test and Replace Battery (if needed)

Sub-steps:
1. If the battery voltage is below 12.4 volts or fails the load test, replace the battery.
2. Remove the old battery by disconnecting both terminals and unbolting the battery hold-down bracket.
3. Install the new battery in reverse order, ensuring terminals are securely tightened.

4. Inspect Starter and Wiring

Sub-steps:
1. Locate the starter motor, typically found near the transmission.
2. Visually inspect the wiring for frays or loose connections.
3. If accessible, use a multimeter to check for voltage at the starter when the ignition is turned on.
4. If no voltage is present, proceed to check the ignition switch and wiring.

5. Replace Starter (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the wiring harness from the starter.
3. Unbolt the starter from its mounting location (usually two or three bolts).
4. Install the new starter, reattach the wiring harness, and bolt it securely.
