Solution

1. Battery Inspection and Replacement

Sub-steps:
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove the battery from the vehicle using a socket set.
- Clean the battery terminals with a wire brush if corroded.
- Test the battery with a load tester; if it fails, replace it with a new one.
- Reinstall the battery, connecting the positive terminal first, then the negative terminal.

2. Fuel System Check

Sub-steps:
- Inspect the fuel lines for any signs of freezing or blockage.
- If necessary, add a fuel line antifreeze to the fuel tank to prevent freezing.
- Replace the fuel filter if it shows signs of clogging.
- Check the fuel pump relay and replace it if faulty.

3. Ignition System Inspection

Sub-steps:
- Remove the ignition coil and inspect for any signs of damage or wear.
- Test the ignition coil with a multimeter to ensure proper resistance.
- Replace the spark plugs if they are worn or fouled.
- Reinstall the ignition components.

4. Coolant Temperature Sensor Replacement

Sub-steps:
- Locate the coolant temperature sensor on the engine.
- Disconnect the electrical connector and remove the sensor using a socket set.
- Install a new coolant temperature sensor and reconnect the electrical connector.
