Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery negative terminal to ensure safety during repairs.
Tools Required: Multimeter, OBD-II scanner, socket set.

2. Battery Inspection and Testing

Remove the battery terminals, starting with the negative terminal.
Clean the battery terminals and cable connectors with a wire brush.
Perform a load test on the battery to ensure it can hold charge under load.
If the battery is weak or failing, replace it with a suitable replacement.

3. Starter Motor Inspection

Locate the starter motor under the vehicle.
Check for loose connections and ensure the wiring is intact.
Use a multimeter to measure the voltage at the starter while the key is in the "start" position.
If voltage is present but the starter does not engage, replace the starter motor.

4. Fuel System Check

Locate the fuel pressure test port on the fuel rail.
Attach a fuel pressure gauge to the test port.
Turn the ignition to the "on" position (do not start) and observe the pressure reading.
If the pressure is below specifications, check for fuel pump operation and replace the fuel pump if necessary.

5. Spark Plug Inspection

Remove the spark plugs using a socket wrench.
Inspect each plug for wear, corrosion, or carbon buildup.
Replace any fouled or worn spark plugs with OEM specifications.
