Solution

1. Preparation

Gather necessary tools and parts before starting.
Tools required: Multimeter, socket set, torque wrench, fuel pressure gauge, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery to prevent electrical shorts.
2. Clean the battery terminals and connectors using a wire brush.
3. Reconnect the battery and test the voltage again.
Safety Warning: Always disconnect the battery before working on electrical systems.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Disconnect the wiring harness from the starter.
3. Use jumper cables to connect the starter motor directly to the battery to check if it engages.
Tools Required: Jumper cables.

4. Fuel System Check

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Attach the fuel pressure gauge and turn the ignition to the "ON" position without starting the engine.
3. Check the fuel pressure reading against the manufacturer's specifications.
Tools Required: Fuel pressure gauge.

5. Ignition System Inspection

Sub-steps:
1. Remove the spark plugs and inspect for wear, carbon build-up, or damage.
2. Test each ignition coil using a multimeter for proper resistance.
3. Replace any faulty spark plugs or ignition coils as needed.
Torque Value: Spark plugs should be torqued to manufacturer specifications (usually around 20 Nm).
