Solution

1. Preparation

Gather tools and materials: multimeter, OBD-II scanner, jumper cables, basic socket set, and safety glasses.
Ensure the vehicle is in a safe location with the parking brake engaged.

2. Address Battery Issues

Check and Clean Battery Terminals:
- Disconnect the negative terminal first, followed by the positive terminal.
- Clean any corrosion from the terminals and cable ends using a wire brush.
- Reconnect terminals, starting with the positive terminal followed by the negative.
Replace the Battery (if necessary):
- If the battery voltage is below 12.6 volts and does not hold a charge, replace it with an OEM or compatible battery.
- Ensure proper installation and torque the battery terminals to 10-15 ft-lbs.

3. Inspect and Replace Starter Motor

Testing the Starter:
- If the engine still does not start after addressing the battery, remove the starter motor.
- Test for continuity with a multimeter to ensure proper operation.
Replace Starter Motor (if faulty):
- Disconnect the battery.
- Remove the wiring harness and mounting bolts from the starter motor.
- Install the new starter motor by reversing the removal steps and ensure all connections are secure.

4. Verify Fuel System

Check Fuel Pump:
- If no fuel pump noise is heard, inspect the fuel pump relay and fuse.
- Replace the fuel pump relay if faulty.
Replace Fuel Pump (if necessary):
- If the fuel pump is determined to be faulty, remove the fuel tank to replace it.
- Ensure to disconnect the battery and relieve fuel pressure before beginning this step.
