Скачать или смотреть Why A Car Starts Then Sputters And Shuts Off

When a car starts but then sputters and shuts off, the problem often lies in the fuel system (such as a failing pump, clogged filter, or bad fuel), ignition system (like faulty spark plugs or sensors), air intake (dirty MAF sensor or vacuum leaks), or engine sensors (such as oxygen or coolant temperature sensors). Issues like a clogged catalytic converter or anti-theft system can also cause this symptom. To diagnose the problem, start by scanning for engine codes, checking fuel pressure, inspecting spark and airflow components, and testing sensors. Notable clues include engine noises, fuel smells, or warning lights. Many of these issues can be fixed by a DIYer, but complex repairs like fuel pump replacement or sensor wiring are best handled by a professional.
