What are the reasons for engine stalling and failure to restart?
2 Answers
Here are the reasons why the engine stalls and cannot be restarted: Fuel depletion: If the fuel is exhausted, there is no fuel, and naturally, the engine cannot start. Mechanical failure: It is highly likely that the timing belt (or chain) is broken, causing timing mechanism disorder. Generally, timing mechanism disorder will lead to valve collision or other more serious derivative faults. Engine maintenance methods: Use qualified engine oil; use qualified coolant and antifreeze; regularly clean the radiator scale; regularly clean engine carbon deposits; regularly replace the three filters of the car; maintain a reasonable speed.
Once when I was driving to the outskirts, the engine suddenly stalled and wouldn't start again, which was extremely frustrating. It could be due to an aging battery with insufficient voltage, or a faulty alternator unable to charge. A broken fuel pump might also prevent gasoline from reaching the engine, and a clogged fuel filter is another common issue. Ignition system failures, such as dirty spark plugs failing to ignite or a damaged ignition coil, could be the culprit. Sensor problems, like a faulty crankshaft position sensor affecting ECU control, or a burned-out starter relay, are also possible. When troubleshooting, first ensure there's sufficient fuel, then check if the battery voltage is within the normal range of 12-14 volts. If you hear the starter motor but the engine doesn't fire, inspect the fuel system; if there's no sound, check the electrical system. Regularly inspecting these components during oil changes can save you from the hassle and extra costs of a roadside breakdown, ensuring both safety and economy. Don't delay—get it checked at a shop promptly.
