Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner, battery terminal cleaner.
Ensure the car is in a well-ventilated area and the engine is off.
Disconnect the battery to avoid shocks during repairs.

2. Battery Inspection and Replacement

Check Battery Condition:
- Use a multimeter to measure voltage. If below 12.4 volts, charge or replace the battery.
Clean Terminals:
- Remove battery cables and clean terminals with a battery terminal cleaner to remove corrosion.
Replace Battery (if necessary):
- Remove the old battery by loosening the hold-down bracket and disconnecting the negative cable first, then the positive.
- Install the new battery by connecting the positive cable first and then the negative. Tighten the hold-down bracket.

3. Starter Motor Testing

Remove the Starter:
- Disconnect the battery again.
- Remove the starter motor by unscrewing the mounting bolts and disconnecting the wiring harness.
Test the Starter:
- Use a multimeter to check the resistance across the starter terminals. If resistance is too high or infinite, replace the starter.

4. Fuel System Check

Inspect Fuel Pump:
- Turn the ignition to the "on" position without starting the engine and listen for the fuel pump's operation sound.
Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail and ensure it meets manufacturer specifications. If pressure is low, consider replacing the fuel pump.
