Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.
Required tools: Multimeter, socket set, wrench set, OBD-II scanner.

2. Battery Inspection and Replacement

Inspect Battery
- Check for corrosion at the terminals. If present, clean with a solution of baking soda and water.
- Tighten any loose connections.
Test Battery
- Use a multimeter to check voltage. If below 12.4 volts, charge or replace the battery.
Replace Battery (if necessary)
- Remove the battery hold-down bracket using the appropriate socket size.
- Disconnect the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal.
- Secure the battery with the hold-down bracket.

3. Starter Motor Inspection and Replacement

Inspect Starter Motor
- Locate the starter motor under the vehicle.
- Check for loose connections and tightness of mounting bolts.
Test Starter Motor
- Perform a voltage drop test across the starter while attempting to start the vehicle.
Replace Starter Motor (if necessary)
- Disconnect electrical connectors from the starter.
- Remove mounting bolts with a socket set and carefully take out the starter motor.
- Install the new starter motor, ensuring connections are tight and secure.
- Reattach electrical connectors and test the starter operation.

4. Fuel System Check

Inspect Fuel Pump Operation
- Turn the ignition key to the "ON" position and listen for the fuel pump activation sound.
Replace Fuel Filter (if blocked)
- Locate the fuel filter and relieve fuel pressure.
- Disconnect the inlet and outlet lines, and remove the filter.
- Install the new fuel filter and reconnect lines securely.
