What to Do When the Car Won't Start Due to Being Too Cold?
1 Answers
Solutions for a car not starting when it's too cold include: cleaning carbon deposits, checking if the water temperature sensor is damaged, inspecting the battery, and addressing ignition system failures. Below are the specific solutions: 1. Clean carbon deposits. Carbon deposits can absorb an appropriate amount of fuel injection, affecting engine startup. The lower the engine temperature, the more fuel is needed for a cold start, and the more carbon deposits there are, the harder it is to start. Engine carbon deposits are typically found on the throttle valve, piston top, and valves. 2. Check if the water temperature sensor is damaged. For example, if the engine temperature is 5 degrees, but the water temperature sensor "tells" the computer the temperature is 20 degrees, the computer will inject fuel based on the 20-degree condition, leading to insufficient fuel injection and failure to start. 3. Inspect the battery. The method to determine is simple: turn on the headlights. If the headlights don't light up at all or are extremely dim, it indicates the battery is dead or the battery connection is poor. 4. Ignition system failure. It is recommended to replace the ignition coil and spark plugs, as an aging ignition coil or poor-performing spark plugs can result in insufficient ignition energy.
