Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal for safety.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect the battery for any physical signs of damage or swelling.
2. Clean the battery terminals using a wire brush and a solution of baking soda and water.
3. If the battery voltage is below 12.4 volts, charge the battery or replace it.
Tools Required: Multimeter, wire brush, baking soda, wrench set for battery terminals.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor; remove any necessary components for access (e.g., air intake duct).
2. With the multimeter, check for voltage at the starter terminal when the ignition key is turned to the start position.
3. If no voltage is present and the battery is good, replace the starter motor.
Tools Required: Socket set, multimeter, screwdriver set.

4. Fuel System Check

Sub-steps:
1. Ensure there is adequate fuel in the tank.
2. If necessary, check the fuel pump operation by turning the ignition to the ON position without starting; listen for the pump priming.
3. If the fuel pump is not functioning, replace it.
Tools Required: Fuel gauge, multimeter.
