Solution

1. Preparation

Gather tools: multimeter, socket set, jumper wire, wrench set.
Ensure the vehicle is in park (or neutral for manual transmissions) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Reconnect the battery terminals and check for tightness. Clean any corrosion using a wire brush.
Sub-step 2: Use a multimeter to test the battery voltage. If it's below 12.4 volts, charge or replace the battery.

3. Starter Solenoid Test

Sub-step 1: Locate the starter solenoid, usually mounted on the starter or fender.
Sub-step 2: Use a jumper wire to bypass the solenoid: connect one end to the battery positive and the other to the solenoid terminal.
Sub-step 3: If the starter engages and the engine cranks, replace the solenoid.

4. Starter Motor Inspection

Sub-step 1: Remove the starter motor from its mounting (usually requires removing bolts with a socket set).
Sub-step 2: Inspect the starter for any signs of wear or damage.
Sub-step 3: Test the starter with a multimeter for continuity and function. Replace if defective.

5. Ignition Switch Check

Sub-step 1: Locate the ignition switch, usually behind the steering column.
Sub-step 2: Test the switch with a multimeter to ensure proper operation. Replace if faulty.
