Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, fuel pressure gauge, socket set, and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery before starting any electrical work.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Remove the negative (-) terminal first, followed by the positive (+) terminal.
- Clean any corrosion with a wire brush and a baking soda solution, if necessary.
- Reconnect terminals securely.
Test Battery Health
- Use a multimeter to measure voltage. If below 12.4 volts, charge the battery.
- If the battery is older than three years or shows signs of weakness, replace it with a new one.

3. Starter Motor Check

Jump-Start the Vehicle
- Connect jumper cables to a working vehicle or a jump starter.
- Attempt to start the engine. If it starts, the battery or connections may be the issue.
Inspect Starter Motor
- If the vehicle still does not start, remove the starter motor and test it according to manufacturer specifications.
- Replace the starter if it fails the test.

4. Fuel System Check

Verify Fuel Pressure
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position without starting the engine and check pressure.
- If pressure is below manufacturer specifications, inspect the fuel pump or fuel filter for blockage and replace as needed.

5. Ignition System Inspection

Check Spark Plugs and Coils
- Remove the spark plugs and inspect for wear or carbon buildup.
- Replace spark plugs if they show signs of excessive wear.
- Test ignition coils for proper operation and replace any faulty coils.
