Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and in "Park" or "Neutral".
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal followed by the positive.
2. Clean the battery terminals and cable connectors with a wire brush to remove corrosion.
3. If the battery is weak (below 12.4 volts), replace it with a new, fully charged battery.
4. Reconnect the terminals, ensuring a tight fit: positive first, then negative.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor; it is typically mounted on the engine near the transmission.
2. Disconnect the wiring harness and the battery cable from the starter.
3. Remove the starter motor mounting bolts using a socket set.
4. Pull the starter motor out and bench test it or replace it if it is faulty.
5. Install the new or tested starter motor by reversing the removal steps.

4. Ignition System Check

Sub-steps:
1. If the starter motor is functional, check the ignition switch by turning the key and ensuring it moves freely and engages.
2. Inspect the ignition relay and replace it if defective.
3. Ensure all connections in the ignition circuit are secure.
