Solution

1. Preparation

Gather tools and parts needed for repair.
Tools Required: Multimeter, socket set, jumper cables, OBD-II scanner.
Ensure the vehicle is in a well-ventilated area and the engine is off.

2. Battery Inspection and Replacement

Sub-step 1: Disconnect the negative (-) terminal of the battery to avoid any electrical shorts.
Sub-step 2: Clean any corrosion from the battery terminals using a wire brush or terminal cleaner.
Sub-step 3: Reconnect the battery terminals firmly and check for tightness.
Sub-step 4: If the battery voltage is below 12.4 volts, replace it with a new battery of the same specifications.

3. Starter Motor Testing and Replacement

Sub-step 1: If the starter motor is suspected, locate it under the vehicle near the transmission.
Sub-step 2: Disconnect the electrical connector and the power cable from the starter.
Sub-step 3: Use jumper cables to connect the starter motor directly to the battery (positive to the main terminal and negative to the casing).
Sub-step 4: If the starter does not engage, replace the starter motor.
Sub-step 5: Reinstall the new starter and reconnect all electrical connections securely.

4. Fuel System Check

Sub-step 1: If the fuel pump is suspected, access the fuel pump relay and test it using the multimeter.
Sub-step 2: If defective, replace the fuel pump relay.
Sub-step 3: If the fuel pump is not operational, replace the fuel pump following manufacturer specifications.
