Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wrenches.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting repairs.

2. Battery Inspection and Replacement

Disconnect the Battery
- Use a socket wrench to disconnect the negative terminal first, followed by the positive terminal.
Inspect Battery Condition
- Check for corrosion on terminals; clean if necessary with a mixture of baking soda and water.
- Test battery health with a multimeter; replace if voltage is low (below 12.4 volts) or if it fails load testing.
Reconnect or Replace
- If the battery is in good condition, securely reconnect the terminals. Otherwise, replace the battery with a new one, ensuring it meets the manufacturer's specifications.

3. Starter Motor Testing

Access the Starter Motor
- Remove any components obstructing access to the starter motor.
Test the Starter Motor
- Use a multimeter to check for power at the starter solenoid while trying to start the engine.
- If there is no power, trace back to the ignition switch and wiring.
Replace if Necessary
- If testing confirms the starter is faulty, remove it using a socket set and replace it with a new starter motor.

4. Fuel System Check

Check Fuel Pump Operation
- Turn the ignition to the 'ON' position (without starting) to listen for the fuel pump activating.
- If the pump is silent, check the fuel pump fuse and relay.
Inspect Fuel Lines
- Look for any signs of freezing or blockage; use a heat gun on frozen lines with caution.
Replace Fuel Filter
- If the fuel filter is clogged, remove it according to the service manual and replace it with a new one.
