3. Starter Motor Test

Sub-step 1: Locate the starter motor, usually near the transmission.
Sub-step 2: Use a multimeter to check if power is reaching the starter when the key is turned.
Sub-step 3: If no power is present, check the ignition switch and related wiring.
Sub-step 4: If power is present but the starter does not engage, replace the starter motor.
Tools Required: Multimeter, socket set.

4. Battery Replacement (if necessary)

Sub-step 1: If the battery voltage is low or the battery is old (over 3-5 years), replace it.
Sub-step 2: Install the new battery, connecting the positive terminal first, followed by the negative.
Tools Required: Socket set.

5. Final Checks

Sub-step 1: Reconnect the battery and ensure all connections are tight.
