Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to ensure safety.
Allow the vehicle to sit for a few minutes before starting work.

2. Inspect Fuses

Locate the fuse box, usually found under the dashboard or hood.
Use a fuse puller or pliers to remove each fuse related to the starting circuit.
Check each fuse visually for continuity; replace any blown fuses with the same amperage rating.

3. Test Starter Motor

Locate the starter motor, typically near the transmission.
Disconnect the electrical connector from the starter.
Use a multimeter to check for voltage at the starter terminal while someone turns the ignition key.
- If voltage is present and the starter does not engage, replace the starter motor.

4. Check Ignition Switch

Remove the steering column cover to access the ignition switch.
Disconnect the wiring harness from the ignition switch.
Use a multimeter to test the switch for continuity when the key is turned to the "Start" position.
- If continuity is not present, replace the ignition switch.

5. Inspect Wiring and Connections

Visually inspect the wiring harness for signs of wear, fraying, or corrosion.
Clean any corroded connections using electrical contact cleaner.
Repair or replace damaged wires as necessary.
