Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and a screwdriver.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical shock.

2. Inspect and Clean Battery Connections

Remove the battery terminals, starting with the negative terminal.
Clean any corrosion from the battery posts and terminals using a wire brush.
Reconnect the terminals securely, ensuring a tight fit.

3. Replace Battery (if necessary)

If the battery voltage is low or the battery is old, replace it.
Remove the old battery by loosening the hold-down clamp and disconnecting the terminals.
Install the new battery, ensuring correct polarity (positive to positive, negative to negative).
Tighten the hold-down clamp and reconnect the terminals securely.

4. Check and Replace Fuses

Locate the fuse box and identify the fuses associated with the starting system.
Remove and inspect each fuse; replace any blown fuses with the same amperage rating.
Reassemble the fuse box and close it securely.

5. Check Fuel Pump Operation

Turn the ignition key to the "ON" position without starting the engine and listen for the fuel pump operation.
If there is no sound, inspect the fuel pump relay and replace it if faulty.
If necessary, replace the fuel pump if it does not operate after checking the relay.

6. Test and Replace Starter Motor (if necessary)

If the starter does not engage when tested, remove the starter motor.
Inspect for any signs of wear or damage; replace it if necessary.
Install the new starter motor, ensuring all connections are secure and torqued to specifications.
