Why does the car make a chugging sound and fail to start?
1 Answers
The reasons why the car makes a chugging sound and fails to start: 1. Fuel pump issue - can be determined by its reaction after power-on; if there's no sound, it indicates a fuel pump problem requiring immediate replacement. 2. Spark plug issues - such as excessive spark plug gap, reaching service life limit, or carbon buildup on spark plugs, necessitating timely replacement. 3. Fuel injector problems - like clogged injectors causing poor atomization or carbon deposits; try cleaning the injectors first, and replace them if cleaning doesn't work.
