Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, remote starter switch, and cleaning materials.
Disconnect the battery negative terminal to ensure safety while working.

2. Inspect and Clean Battery Connections

Remove the battery terminals (negative first, then positive).
Clean the terminals and cable ends with a wire brush or terminal cleaner.
Reconnect the battery terminals tightly (positive first, then negative).

3. Test and Replace Battery (if necessary)

Use a multimeter to check the voltage; if below 12.4 volts, charge the battery.
If the battery is old (over 3-5 years) or fails to hold a charge, replace it with a new one.
Ensure the new battery is fully charged before installation.

4. Test Starter Motor

Reconnect the battery and use a remote starter switch to bypass the ignition system.
If the starter engages and the engine cranks, replace the ignition switch.
If the starter does not engage, replace the starter motor.

5. Check Ground Connections

Inspect the ground straps from the battery to the engine and body for any corrosion or breaks.
Clean or replace any damaged ground connections to ensure a good electrical path.
