Routine maintenance keeps cars functioning correctly. But it doesn’t permanently eradicate malfunctions. For example, you\u2019ve probably heard of the ultimate car nightmare \u2013 a car shutting off while driving.<\/p>\n\n\n\n

\"Car<\/figure>\n\n\n\n

Cars shut off while driving primarily due to fuel system issues. However, it is possible for other factors to be at play.<\/strong> Read on to discover why your car shuts off while driving and how to fix them.<\/p>\n\n\n\n

<\/a>What Would Cause a Car To Shut Off While Driving?<\/h2>\n\n\n\n

Here are some reasons behind your car shutting off while driving.<\/p>\n\n\n\n

<\/a>Fuel Doesn’t Reach the Combustion Chamber<\/h3>\n\n\n\n

Fuel powers the engine to function at optimum levels. So when it clogs and fails to reach the combustion tanks, your car can easily shut off. This scenario can occur because of the following reasons:<\/p>\n\n\n\n

<\/a>Faulty Fuel Pump<\/h4>\n\n\n\n

An effective fuel pump<\/a> should transfer fuel from the tank to the carburetor or injector. This way, it keeps the fuel pressure above an appropriate level.<\/p>\n\n\n\n

When the pump is faulty, the fuel pressure remains below the required amount to start the engine, and your car can shut off randomly.<\/p>\n\n\n\n

<\/a>Empty Fuel Tank<\/h4>\n\n\n\n

Your car can simply shut down because its gas tank is empty. This situation occurs primarily when your gas gauge is faulty. This way, you can’t know the actual fuel amount in the car.<\/p>\n\n\n\n

<\/a>Faulty Alternator<\/h3>\n\n\n\n

Fuel alternators produce constant streams of electricity from the car’s mechanical energy. As a result, it runs different electrical parts such as stereo, dome lights, and conditioning units.<\/p>\n\n\n\n

It also charges the car battery<\/a>. So, if the alternator is faulty, your car gets insufficient electrical energy, and the battery dies.<\/p>\n\n\n\n

You’ll usually get a flashing dash when your alternator is faulty. So, pay close attention to notice when your car begins to receive intermittent power.<\/p>\n\n\n\n

However, you can still test the alternator out using the following tips:<\/p>\n\n\n\n

    \n
  1. Leave the car engine running for some minutes.<\/li>\n\n\n\n
  2. Turn off all the lights, including the stereo and dashboard.<\/li>\n\n\n\n
  3. Use a multimeter to test the battery.<\/li>\n\n\n\n
  4. Check your test results.<\/li>\n<\/ol>\n\n\n\n

    Healthy alternators produce 13.1V and 14.1V at idle speed. If the test results indicate your faulty alternator, contact a professional for further assessment.<\/p>\n\n\n\n

    <\/a>Insufficient Air Delivery to the Engine<\/h3>\n\n\n\n

    Your engine may receive insufficient air because of the following reasons:<\/p>\n\n\n\n

    <\/a>Faulty Throttle Body<\/h4>\n\n\n\n

    A throttle body<\/a> controls the engine power by regulating the fuel supply. When faulty, it allows insufficient air into the gas engine, leading to random shut-offs.<\/p>\n\n\n\n

    <\/a>Clogged Air Filters<\/h4>\n\n\n\n

    When the air filters<\/a> get clogged, it leaves a small space for air to enter the car engine, leading to shut-offs.<\/p>\n\n\n\n

    <\/a>Malfunctioned Sensors in the Electronic System<\/h3>\n\n\n\n

    Modern car models highly rely on electrical systems to function correctly. But, these systems can malfunction<\/a> and lead to shut-offs because of the following reasons:<\/p>\n\n\n\n

    <\/a>Faulty MAF Sensor<\/h4>\n\n\n\n

    MAF sensors control the air delivered into the engine system. Below are some of the things that indicate your mass airflow sensor is faulty:<\/p>\n\n\n\n
