Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, battery terminal cleaning brush.
Ensure the vehicle is in a safe, well-ventilated area and park it on a level surface.
Disconnect the battery to prevent any electrical shorts during inspection.

2. Battery Inspection and Replacement

Check Battery Condition
- Use a multimeter to measure voltage; it should be at least 12.6V.
- If below 12.4V, consider charging or replacing the battery.
Clean Battery Terminals
- Use a battery terminal cleaning brush to remove corrosion.
- Ensure terminals are tight and secure.
Replace Battery (if necessary)
- Remove the battery hold-down bracket with a socket set.
- Disconnect the negative terminal first, followed by the positive terminal.
- Install the new battery by connecting the positive terminal first, then the negative.
- Reattach the battery hold-down bracket.

3. Starter and Ignition System Check

Test Starter Motor
- Locate the starter motor and check connections for tightness and cleanliness.
- Use a multimeter to test the voltage at the starter while someone turns the key to the start position.
- If no voltage is present, check the ignition switch and wiring.
Inspect Ignition System
- Remove spark plugs and inspect for wear or fouling; replace if necessary.
- Test ignition coils for proper resistance using a multimeter; replace as needed.

4. Fuel System Verification

Check Fuel Pressure
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position (not starting) and check pressure readings.
- If pressure is low, inspect the fuel pump and filter.
