Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Battery Replacement

Remove the old battery:
- Unfasten the positive (+) terminal first, then the negative (-) terminal.
- Remove any securing brackets and lift the battery out.
Install the new battery:
- Place the new battery in the tray and secure it with brackets.
- Connect the negative (-) terminal first, followed by the positive (+) terminal.
- Ensure terminals are tight and free of corrosion.

3. Starter Motor Inspection

Remove the starter motor:
- Disconnect the battery if not done earlier.
- Unbolt the starter from its mounting position.
- Disconnect the electrical wiring from the starter.
Test the starter motor:
- Connect the multimeter to the starter terminals and activate the ignition.
- Check for proper voltage; replace the starter if voltage is inadequate.

4. Fuel System Check

Inspect the fuel pump:
- Locate the fuel pump relay and remove it.
- Check the relay for continuity using a multimeter.
- If faulty, replace the relay and reconnect.
Test fuel pressure:
- Attach a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "On" position without starting the engine; check for adequate fuel pressure.
