This car doesn't start well in cold weather. Why?

There are many reasons why the engine can't start. The main inspection items are as follows: 1, the battery voltage is low; Specific detection method: test the battery voltage with a voltage range of three meters. If it is lower than 10V, it is recommended to replace it. If it is around 1 1V, it is barely used; Be prepared to be replaced. 12V or more is ok, but other reasons should be found. 2. Check whether it is caused by carbon deposition. 3. Check, test and replace the spark plug.

4. Confirm the quality of the added oil.

5. Check the ignition switch. 6. Test and inspect the starter, gasoline pump and sensor. 7. Don't start it immediately after being electrified again, wait for 30 seconds to 1 minute, and then ignite; See if it works. In any of the above cases, please note that when you can't get a taxi at one time, you must call it again every 15-30 seconds to protect the battery from excessive power generation and prolong its service life.
