Solution

1. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative battery terminal first, then the positive.
2. Clean the battery terminals with a wire brush.
3. Test the battery with a multimeter; replace if voltage is below 12.4V.
4. Reconnect the battery terminals (positive first, then negative).

2. Starter Motor Testing

Sub-steps:
1. Remove the starter motor from the vehicle.
2. Use a multimeter to check the resistance; replace if faulty.
3. Reinstall the starter motor and ensure all connections are tight.

3. Fuel System Check

Sub-steps:
1. Check the fuel pump operation by listening for the pump sound when turning the ignition key to the ON position.
2. Use a fuel pressure gauge to measure fuel pressure; it should be within manufacturer specifications.
3. Replace the fuel filter if clogged or if fuel pressure is low.

4. Engine Oil Change

Sub-steps:
1. Drain the old engine oil while the engine is warm.
2. Replace with the appropriate viscosity oil for cold weather (e.g., 0W-20).
3. Replace the oil filter and check for leaks after filling with oil.
