Solution

1. Preparation

Gather tools and parts needed:
- Tools: Multimeter, socket set, wrench set, battery terminal cleaner, screwdriver set
- Parts: New battery (if necessary), starter relay (if faulty), ignition switch (if needed)
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Battery Inspection and Replacement

Disconnect the Battery:
- Use a wrench to remove the negative (-) terminal from the battery.
- Then remove the positive (+) terminal.
Clean Battery Terminals:
- Use a battery terminal cleaner or a wire brush to remove corrosion from both terminals.
- Reconnect the terminals securely.
Test or Replace Battery:
- If voltage is below 12.4 volts, use a battery charger to recharge.
- If the battery is old or damaged (over 3-5 years), replace it with a new one.

3. Starter Relay and Ignition System Check

Inspect Starter Relay:
- Locate the fuse box and identify the starter relay.
- Swap it with another relay of the same type to test functionality.
Test the Ignition Switch:
- Remove the steering column cover to access the ignition switch.
- Use a multimeter to check for continuity when the key is turned to the start position. Replace if faulty.

4. Starter Inspection

Check Starter Connections:
- Ensure the starter mounting bolts are tight.
- Inspect the wiring connections on the starter solenoid for damage.
Test the Starter:
- If all else checks out, perform a bench test on the starter using jumper cables to ensure it engages.
