Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrenches, and safety gloves.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Battery Inspection and Replacement

1.1 Remove the battery from the vehicle:
- Use a socket set to loosen and remove the battery hold-down clamp.
- Disconnect the positive terminal first, followed by the negative terminal.
- Carefully lift the battery out of the compartment.
1.2 Clean battery terminals:
- Use a wire brush to remove corrosion from the terminals and cable ends.
1.3 Test or replace the battery:
- If the battery voltage is below 12.4 volts, charge or replace it with a new one rated for cold weather.

3. Starter Motor Inspection/Replacement

3.1 Inspect the starter motor:
- Locate the starter motor, usually mounted near the transmission.
- Check electrical connections for corrosion and tightness.
3.2 Test the starter motor:
- Connect a multimeter to the starter terminals and crank the engine to check for voltage drop.
- If the starter fails to engage, remove it using a socket set and replace it with a new starter.

4. Fuel System Check

4.1 Check fuel pressure:
- Attach a fuel pressure gauge to the fuel rail and crank the engine to check the pressure.
- If the pressure is low, inspect the fuel pump and fuel filter for blockages or failures.
