Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and in "Park" or "Neutral."
Disconnect the negative battery terminal to avoid accidental short circuits.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect the battery terminals for corrosion. Clean them with a wire brush if necessary.
2. If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery.
  - Tools Required: Multimeter, battery terminal cleaner.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor (usually near the engine block).
2. Test the starter motor by applying direct battery voltage to the starter terminal using jumper cables.
3. If the starter does not engage, remove it from the vehicle:
  - Disconnect the wiring harness and remove securing bolts.
4. Replace the starter motor with a new unit if necessary.
  - Tools Required: Socket set, wrenches, jumper cables.

4. Inspect and Repair Electrical Connections

Sub-steps:
1. Check all grounding points for corrosion or loose connections.
2. Repair or replace any damaged wires or connectors in the starting circuit.
  - Tools Required: Socket set, wire crimpers, electrical tape.

5. Reassembly

Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.
Ensure that all tools are removed from the engine bay.
