Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect negative battery terminal for safety.

2. Battery Inspection

Tools Required: Multimeter, wrench
- Use the multimeter to measure the battery voltage.
- If the voltage is low, charge or replace the battery as necessary.
- Clean battery terminals and reconnect them securely.

3. Starter Motor Testing

Tools Required: Jumper wire, wrench
- Locate the starter motor.
- Connect a jumper wire from the battery positive terminal to the starter motor’s positive terminal.
- If the starter engages, it may need replacement; if not, continue troubleshooting.

4. Fuse Check

Tools Required: Fuse puller or pliers
- Locate the fuse box and identify the starter-related fuses.
- Remove and inspect each fuse; replace any that are blown.

5. Ignition Switch Inspection

Tools Required: Multimeter, screwdriver
- Access the ignition switch; use the multimeter to check for continuity when the key is turned to the start position.
- If no continuity is detected, replace the ignition switch.

6. Ground Connection Verification

Tools Required: Wrench
- Inspect and clean ground connections between the battery, engine block, and chassis.
- Tighten any loose connections found.
