Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, torque wrench, and safety gloves.
Ensure the vehicle is in park and the ignition is off.
Disconnect the battery to prevent accidental short circuits.

2. Battery Inspection and Replacement

Step 2.1: Remove the negative (-) battery terminal first, then the positive (+) terminal using a socket set.
Step 2.2: Inspect the battery for bulging, leakage, or corrosion. If any are present, replace the battery.
Step 2.3: If the battery is good, clean the terminals with a wire brush and reconnect the terminals securely (positive first, then negative).

3. Starter Motor Inspection

Step 3.1: Locate the starter motor beneath the vehicle. Disconnect the battery again for safety.
Step 3.2: Remove the electrical connector from the starter solenoid.
Step 3.3: Using a multimeter, check for voltage at the solenoid terminal while an assistant turns the key to the start position. If there is no voltage, the issue may lie in the ignition switch or wiring.
Step 3.4: If voltage is present, remove the starter motor from its mounting using a socket set and inspect it for wear or damage. Replace if necessary.

4. Reassembly

Step 4.1: Reinstall the starter motor in reverse order, ensuring all connections are tight.
Step 4.2: Reconnect the battery terminals (positive first, then negative).
Step 4.3: Test the vehicle to ensure it starts properly.
