Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is in a safe and well-ventilated area.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Sub-step 1: Clean battery terminals using a wire brush if corrosion is present.
Sub-step 2: If the battery voltage is low (below 12.4V), jump-start the vehicle or charge the battery using a battery charger.
Sub-step 3: If the battery is more than three years old or fails to hold a charge, replace it with a new battery of the same specifications.

3. Starter Motor Inspection

Sub-step 1: Remove the starter motor from the engine. Use a socket set to detach the mounting bolts.
Sub-step 2: Test the starter motor with a multimeter; it should draw the correct amperage when engaged.
Sub-step 3: If the starter fails the test, replace it with a new unit.

4. Fuel System Check

Sub-step 1: Inspect the fuel lines for any blockages or leaks.
Sub-step 2: Test the fuel pump operation by listening for a humming sound when the ignition is turned to the "ON" position.
Sub-step 3: If the fuel pump does not operate, replace it with a compatible unit.
