Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Check

Tools Required: Multimeter, wrench
Reconnect the battery and measure the voltage with a multimeter. If voltage is less than 12.4 volts, recharge or replace the battery.
Safety Warning: Always connect the positive terminal first when connecting the battery.

3. Clean Battery Terminals

Tools Required: Wire brush, battery terminal cleaner
Remove the battery terminals (negative first, then positive).
Clean terminals and cable ends thoroughly to remove corrosion.
Reconnect terminals securely, starting with the positive terminal.

4. Check Starter Relay

Tools Required: None
Locate the starter relay in the fuse box (refer to owner’s manual).
Swap the starter relay with another relay of the same type to test functionality.

5. Inspect Fuses

Tools Required: Fuse puller or pliers
Check all fuses related to the starting system in the fuse box.
Replace any blown fuses with the same amperage rating.

6. Test Starter Motor

Tools Required: Multimeter, wrench
Locate the starter motor and check for voltage at the terminal while a helper turns the key to the start position.
If there is voltage but the starter does not engage, the starter motor may need replacement.
