Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a well-ventilated area and parked on a flat surface.
Disconnect the negative battery terminal.

2. Battery Inspection

Inspect Battery Health
- Use a multimeter to check the battery voltage.
- If the voltage is below 12.4 volts, jump-start or replace the battery.
Clean Terminals
- Remove the battery cables and clean any corrosion with a wire brush.
- Reconnect the cables securely.

3. Starter Motor Check

Test the Starter
- Locate the starter motor (typically near the engine's transmission).
- Use a jumper wire to apply power directly to the starter terminal.
- If the starter engages and the engine turns over, replace the starter.

4. Fuel System Check

Test Fuel Pump
- Reconnect the battery.
- Turn the ignition to the ON position without starting the engine and listen for the fuel pump.
- If no sound, check the fuel pump fuse and relay. Replace if necessary.
- If the pump is faulty, replace it.

5. Electrical System Check

Inspect Fuses
- Check the fuse box for any blown fuses related to the starting system or fuel system.
- Replace any blown fuses with the correct amperage rating.

6. Final Steps

Reconnect the negative battery terminal.
Test the vehicle by attempting to start it again.
