Solution

1. Battery Inspection and Maintenance

Tools Required: Multimeter, wire brush, wrenches
Measure the battery voltage; it should be at least 12.4 volts. If below, recharge or replace the battery.
Clean battery terminals using a wire brush to remove corrosion and ensure a tight connection.
If the battery is older than 3-5 years, consider replacing it.

2. Engine Oil Change

Tools Required: Socket set, oil filter wrench, oil catch pan
Check the engine oil viscosity; it should meet the manufacturer's specifications for cold weather (typically 0W-20).
If the oil is too thick, drain the old oil and replace it with the correct viscosity oil.
Replace the oil filter during the oil change.

3. Fuel System Check

Tools Required: Fuel pressure gauge
Inspect the fuel filter and replace if it is clogged.
Check the fuel pump operation by measuring the fuel pressure; it should be within the manufacturer's specifications.
Use a fuel additive designed for cold weather to improve fuel flow if necessary.

4. Starter Motor Inspection

Tools Required: Multimeter, socket set
Test the starter motor by measuring voltage at the starter during cranking; should be around 10 volts or more.
If voltage is low, check wiring and connections for damage or corrosion.
Replace the starter motor if it fails to operate properly.
