What causes a car to die while driving and refuse to start?
Running out of fuel - This may seem ridiculous, but it happens to a lot of people. Drivers frequently fail to refuel their vehicles and run out of fuel in the middle of the road. Another reason for this is when the fuel gauge does not give the correct reading. For example, ...
... it may indicate that you have half a tank of fuel remaining, but the tank is empty.
Bad Fuel Pump - Another common cause of engine stalling is a problem with the fuel pump. The fuel pump's job is to deliver fuel from the fuel tank to the engine in order for the combustion process to be completed. The delivered fuel, on the other hand, must have a certain pressure as well as a certain flow rate. The car stalls and stops working if the pressure or flow rate falls below the required level. You could also have an issue with the fuel filter. The filter is installed after the fuel pump to clean the fuel before it enters the engine. It removes any impurities and stains that may clog the fuel line and prevent fuel from reaching the engine. Look for full car service near me garage and have this issue rectified.
Ignition Switch Failure - The ignition switch is the main gate that connects the current from the battery to the car accessories and starter in order for the car to start. If your ignition switch fails, your car may stall because the internal contacts are worn out. As a result of the heat and hard vibrations, voltage is lost. The ignition switch is prone to wear and tear in older vehicles with high mileage. This results in poor contact between the two contacts.
Low Charge Alternator - If you're driving your car and the dashboard battery lamp suddenly illuminates, it's an indication that the car will run for a few minutes before stopping. This vehicle will not start again until you replace the battery. This occurs because no power is being supplied to the vehicle. Electricity is required for the engine to function. For example, spark plugs require electricity to generate a spark to complete the combustion. The operation of the fuel pump is also dependent on the alternator's supply of electricity.
Faulty Car Battery - This is a common problem that many people face because they believe that the car only uses the battery during the initial startup. However, this is not the case. When the car battery isn't working properly or is in poor condition, the alternator has to work harder to keep the voltage stable enough to keep the engine running. Running an overworked alternator puts additional strain on the engine, causing it to stall. If your battery is faulty, the car will die while driving, will not start, and will only click.
Wrong Signal Sensors - There are several sensors in modern cars that are in charge of engine management. These sensors continue to read the movements and send commands to the ECU. The ECU then sends signals to actuators such as spark plugs and injectors in a specific order and at a specific time. If the sensors fail, the ECU receives incorrect information about the engine's status. As a result, the actuators will receive incorrect commands, such as no sparkplug signal or no injector pulse. It eventually leads to poor performance and a car that shuts down while driving and won't start again. When booking your car in at a car service near me garage, request the car mechanic to also perform a full vehicle health check to avoid any further issues.
What to Do If Your Car Breaks Down While You're Driving
When you find yourself in this situation, your first priority should always be safety. Your safety, as well as the safety of those on the road around you, is of the utmost importance. Once you're safe, conduct a quick search for clues as to why this is happening. These pointers may assist you in safely exiting this situation:
Get your car off the road or to the far-left side of it. The first step is to activate the hazard lights to alert oncoming traffic that there is a problem with your vehicle. The steering may be difficult but do your best to deal with it and park the vehicle using the handbrakes because the normal brake pedal will not function normally.
A failure in the battery charging system is indicated by a warning light on the dashboard. It could be an issue with the alternator or the battery. Examine all electrical systems, connectors, and terminals. If not, inspect the drive belt for damage and retighten it if possible.
Check for a clogged fuel filter if the car dies while driving but restarts. It could also be the result of a faulty fuel pump that is unable to maintain a consistent pressure. Check the fuel pressure and fuel lines to easily track down and diagnose the problem.
If the car stops while driving and then restarts after a short period of time or after it has cooled down, there is a problem with the engine management system. In this case, you must carefully inspect the position sensors. Examine the crank position sensor because if it is faulty, it will provide the incorrect position for the crankshaft, resulting in a misfiring order that will cause the engine to stall.
