Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery negative terminal to ensure safety.
Tools Required: Socket set, multimeter, OBD-II scanner, fuse tester, wire brush.

2. Battery Inspection and Replacement

Inspect the battery terminals for corrosion or damage.
- Use a wire brush to clean any corrosion.
- Tighten the connections securely.
If the battery voltage is low (below 12.4 volts), replace the battery.
- Remove the battery using a socket set.
- Install the new battery and ensure the terminals are clean and tight.

3. Starter Motor Testing and Replacement

Locate the starter motor (usually near the transmission).
Disconnect the wiring harness from the starter.
Use a multimeter to check for continuity.
If the starter motor is faulty, remove it:
- Unbolt the starter motor using a socket set.
- Install the new starter motor, ensuring that it is securely fastened.
- Reconnect the wiring harness.

4. Fuel System Check

If the starter motor is functional, check the fuel pump.
Remove the fuel pump relay from the fuse box.
Test the relay for continuity using a multimeter.
If faulty, replace the relay.
If the fuel pump is suspected to be non-functional, replace it:
- Access the fuel pump through the rear seat or trunk.
- Disconnect the fuel lines and electrical connector.
- Remove the old fuel pump and install the new one.
