Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, fuel pressure gauge.
Ensure vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to work safely on electrical components.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from terminals and cable ends using a wire brush.
Reconnect the battery securely, starting with the positive terminal.

3. Starter Motor Test

Locate the starter motor (usually near the transmission).
Disconnect the wiring harness from the starter.
Use jumper cables to connect the starter directly to the battery; listen for operation.
If the starter does not engage, replace it.

4. Fuel System Check

Locate the fuel rail and connect the fuel pressure gauge.
Turn the ignition to the "ON" position (do not start) and check for specified fuel pressure.
If pressure is low, inspect the fuel pump and replace if necessary.

5. Spark Plug and Ignition Coil Check

Remove the spark plugs using a socket wrench.
Inspect the spark plugs for wear or fouling; replace if necessary.
Test the ignition coils with a multimeter and replace any faulty coils.
