Solution

1. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure voltage; a healthy battery should read around 12.6 volts or higher.
- If the voltage is below 12.4 volts, recharge the battery or consider replacement.
Clean Battery Terminals
- Disconnect the negative terminal first, then the positive terminal.
- Clean terminals and connectors with a wire brush to remove corrosion.
- Reconnect terminals, starting with the positive first.

2. Fuel System Check

Inspect Fuel Quality
- If necessary, drain the fuel tank and replace with fresh fuel.
- Add a fuel system cleaner to prevent gelling in cold weather.
Examine Fuel Pump Operation
- Listen for the fuel pump activation sound when turning the ignition on (without starting).
- If not audible, check fuses and relay for the fuel pump.

3. Engine Oil Change

Assess Oil Viscosity
- Check the owner’s manual for the recommended oil viscosity for cold weather.
- If the oil is too thick, drain and replace with a suitable low-temperature oil.

4. Starter Motor Inspection

Check Starter Operation
- Test the starter motor with a multimeter to ensure it is drawing the correct voltage.
- If the starter is faulty, remove it and replace it with a new or refurbished unit.
