Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Clean battery terminals using a wire brush if corrosion is present.
Sub-step 2: Tighten the terminal connections to ensure a secure fit.
Sub-step 3: If the battery voltage is below 12.4 volts, charge the battery using a battery charger or jump-start the vehicle.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor under the vehicle.
Sub-step 2: Use a multimeter to check the voltage at the starter solenoid while someone turns the key to the start position.
Sub-step 3: If voltage is present but the starter does not engage, replace the starter motor.

4. Fuel System Check

Sub-step 1: If the starter is functional, check the fuel pump relay and fuse.
Sub-step 2: Replace any faulty relays or fuses.
Sub-step 3: If the pump is not functioning, replace the fuel pump.

5. Reassembly

Sub-step 1: Reconnect the negative battery terminal securely.
Sub-step 2: Ensure all tools are removed from the engine bay.
Sub-step 3: Start the vehicle to ensure proper operation.
