Solution

1. Battery Maintenance

Sub-step 1: Clean battery terminals with a wire brush and a mixture of baking soda and water to remove corrosion.
Sub-step 2: Charge the battery using a battery charger until it reaches full capacity (12.6 volts).
Sub-step 3: If the battery is old (over 3-5 years), consider replacing it with a new battery that meets factory specifications.

2. Fuel System Inspection

Sub-step 1: Ensure there is sufficient fuel in the tank; add fuel if below a quarter tank.
Sub-step 2: Inspect the fuel pump operation by listening for its sound when the ignition is turned to the ON position (not starting).
Sub-step 3: If the pump is not functioning, replace the fuel pump as necessary.

3. Starter System Check

Sub-step 1: Remove the starter motor for inspection.
Sub-step 2: Test the starter motor with a multimeter; it should draw the specified amperage.
Sub-step 3: If the starter motor is faulty, replace it according to vehicle specifications.

4. Reassemble and Test

Sub-step 1: Reconnect all components securely and ensure there are no loose connections.
Sub-step 2: Start the vehicle to verify the repairs were successful.
