The cold weather is coming and with it, the chance of having to deal with a car that won’t start. Whether it’s because of the salt on the roads or something more sinister, sometimes our cars just don’t want to turn over. In this article, we’re going to show you how to diagnose and fix a car that won’t start in freezing temperatures.
Check the Battery
If you’re having difficulty getting your car to start, the first thing to check is the battery. If it’s fully charged and the battery light is on, there’s probably a problem with the starter. Check for corrosion or damage on the battery terminals, and clean them if necessary. If that doesn’t solve the problem, you may need to replace the starter.
Replace the Fuel Filter
One common issue with cars that won’t start is a clogged fuel filter. If the fuel filter is not able to properly clean the fuel lines, the engine will not be able to get the necessary fuel and will not start.
If your car won’t start, the first thing you should do is check the battery and cables. Make sure there isn’t a short or damage. Next, check for any clogged filters. Clean out any debris or dirt that may have accumulated in the filter. Finally, try starting the car again – if it still won’t start, then you may need to replace the fuel filter.
Change the Oil and Cabin Filters
If your car won’t start, the first thing you should do is check the oil. If it’s low, add more. Next, check the cabin filters. If they’re dirty, replace them.
Check for Error Codes
If your car won’t start, the first thing you should do is try to jump it. If that doesn’t work, the next step is to try to start the car by turning the key all of the way to the left or right and then revving the engine. If you still can’t get the car to start, there may be an error code that you need to check.
Some of the most common error codes are P0171, P0174, and P0182. P0171 indicates a problem with the fuel injectors, P0174 indicates a problem with the spark plugs or coil packs, and P0182 indicates a problem with one of the engines’ cylinders. If you see one of these codes, make sure to drive to a nearby mechanic and have them take a look at your car.
