Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before beginning work.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery cover and inspect connections for corrosion.
2. Use a multimeter to check battery voltage; it should be at least 12.6 volts.
3. If the battery is faulty or weak, replace it with a new one that meets OEM specifications.
4. Reconnect the terminals, ensuring they are tight and clean.

3. Fuel System Check

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Start the engine and check the fuel pressure; it should match manufacturer specifications.
3. If pressure is low, inspect the fuel pump and fuel filter for clogs or failures.
4. Replace any faulty components as necessary.

4. Engine Coolant Temperature Sensor Replacement

Sub-steps:
1. Locate the coolant temperature sensor on the engine block.
2. Disconnect the electrical connector and remove the sensor using a socket set.
3. Install the new sensor and reconnect the electrical connector.
4. Clear any stored error codes using the OBD-II scanner.

5. Spark Plug and Ignition System Check

Sub-steps:
1. Remove the spark plugs using a socket set.
2. Inspect them for wear, carbon buildup, or damage; replace if necessary.
3. Check the ignition coils for proper operation and replace any that are faulty.
4. Reinstall the spark plugs to the manufacturer's torque specifications.
