Causes of cars stalling in the middle of the road and how to handle them

The car stalled in the middle of the road

While driving, a car stalling is not a rare situation for many drivers. However, not everyone knows what the cause is and how to handle it. Don’t worry, CarOn will help you answer right below this article!

Out of gas

The car stalled because it ran out of gas

This is a case that happens quite often, mainly due to subjectivity or maybe being too busy driving and forgetting to pay attention to the remaining ingredients in the tank. Running out of fuel will cause the engine to stall, which is very dangerous and can damage the fuel pump.

How to handle physical

When your car runs out of gas and won’t start, there are a few things to note: Do not start the engine for longer than 10 seconds at a time. Otherwise, it will damage the starter. If the engine does not start the first time, wait about 20 seconds before starting again.

When your car runs out of gas and won’t start, add at least 10 Liters (2.6 US gal, 2.2 Imp gal) of fuel, and try to start the engine again. Because air may be present in the fuel line when the vehicle runs out of fuel, the engine may take longer to start. If the engine does not start the first time, try starting it again a few times. If the engine still cannot start, contact a repair specialist.

Exhausted or burnt lubricating oil

The car stalls because it runs out or burns out lubricating oil

Don’t wait for the car to run 5,000 – 10,000km before changing the oil because 5,000km on the highway is completely different from 5,000km on a crowded street.

Reason

Usually comes from the car owner replacing poor quality lubricating oil, leading to oil burn or sludge buildup in the engine compartment. In some cases, oil leaks also cause oil depletion. Without lubrication, the parts in the engine will rub against each other, the engine will bind and even the arm will break. Car owners need to pay attention to the engine oil pressure warning light and the undercarriage after moving. If oil leaks, the car owner will notice liquid flowing down to the area underneath the car.

Treatment

Immediately after discovery, you need to take it to the Garage for maintenance and change the oil immediately, remember to remind the handler to add the correct dosage and type of oil suitable for your car model!

The cooling system is broken

The cooling system is broken

A problem or damage to the cooling system is one of the reasons why the engine overheats and causes the car to stall suddenly.

Signal

  • The cooling water has a strange color and contains rust residue.
  • The water pump does not circulate the cooling water flow.
  • Water pipes in the cooling system leak
  • The water tank is clogged.
  • The radiator fan does not start.

Treatment

When you see the coolant temperature rise abnormally high, you should quickly park your car in a safe, shaded location. Turn off the engine, air conditioner and other equipment in the car. At this time, the engine compartment is very hot You should not open the hood to check immediately But wait until the machine cools down completely

If you see that your car has run out of coolant, add more. If there is no cooling water available, you can temporarily use filtered water. Then wait for the engine temperature to drop then take the car to the garage to have it checked immediately.

Engine oil problem

The vehicle is leaking oil, causing the engine to be deficient, or using poor quality, expired, degraded oil, etc., which not only affects the lubrication of engine parts, but also causes the engine to overheat. Heat leads to sudden engine stalling. Because in addition to lubricating, engine oil also has a cooling function.

Engine oil problem

If the car is out of oil or the oil is covered with sludge, clay, etc., the internal parts of the engine will not be cooled effectively. In addition, because the oil’s lubricating ability is less effective, friction will increase, thereby increasing the engine’s temperature. This is also one of the reasons why the engine overheats and the car suddenly stalls.

Signal

  • The oil light is on
  • The oil turns black and contains grit
  • There is a strange noise from the car engine
  • The vehicle slows down or accelerates slowly
  • The oil level is always at the Min level of the oil dipstick

Treatment

If you find your car is low on oil, add more. If the car’s oil is old or has changed quality, you should drain the oil and replace it with new oil. Then you should take the car to the garage to be carefully inspected.

Fuel filter clogged

Fuel filter clogged

The fuel filter is responsible for filtering dirt and impurities from the fuel before entering the engine. So over time, the fuel filter will become dirty and clogged. This will cause fuel

Signal .

  • The car engine makes a strange noise
  • The engine is weak, vibrates, has difficulty starting, etc.
  • The exhaust pipe shows sparks and a lot of exhaust gas
  • The car consumes more fuel
  • Engine starts outside or quits

Treatment

In order for the car to operate, you should press the accelerator pedal many times to increase the pump power to provide enough gasoline for the car to operate and go to the center or maintenance garage or repair to fix the vehicle’s condition.

The fuel pump and high pressure oil pump are broken

The gasoline pump (gasoline engine) and high-pressure oil pump (diesel engine) are the parts responsible for pumping fuel through the nozzle into the combustion chamber, performing the combustion process to generate work. Therefore, if the fuel pump is broken, the combustion process will not take place or will not take place effectively. This error is also one of the causes of the car suddenly stalling

Treatment

When the fuel pump has a problem, the only way you can do it is to take the car to the garage so that technicians can check and provide reasonable repair measures to avoid the car stalling in the middle of the road. If the damage is severe, it is best to replace the fuel pump.

Pressure regulator valve is faulty

The pressure regulator valve is responsible for ensuring constant fuel pressure in the divider pipes. If the pressure regulator valve is faulty, the fuel pressure will not be stable, resulting in too high or too low pressure. This greatly affects engine power. This is also one of the reasons why engines fail and cars stall in the middle of the road.

Signal

  • When the pressure regulator valve is faulty
  • Vehicles often show signs of reduced engine power
  • Weak acceleration
  • The car consumes more fuel
  • The car is emitting black smoke…

Treatment

When the pressure regulator valve fails, the best way is to check and replace the pressure regulator valve as soon as possible.

Fuel injector clogged

Fuel injector clogged

Car injectors are responsible for spraying fuel into the combustion chamber to carry out the combustion of the gas and fuel mixture. Even though the fuel is filtered before entering the injector, after a long period of operation, the injector will still be covered with dirt. If not cleaned for a long time, it will cause the injector to become clogged and clogged.

When the injector is clogged, fuel cannot enter the combustion chamber or not enough fuel enters the combustion chamber. Spray flow, spray particle size and injection time are incorrect. This greatly affects the combustion process.

Signal

  • The engine stalled
  • Accelerate slowly, when missing the throttle
  • Maximum speed threshold not reached
  • Cannot start the engine
  • The throttle is difficult to control
  • Display indicator light on electronic clock
  • The strong smell of gasoline from the engine entered the cockpit
  • Through fuel injector

Treatment

Below are methods that car owners can follow before contacting a repair unit. However, if the problem is too serious, the driver should not hesitate to seek help from experts. Here are some simple steps you can take:

– Check fuel filters and replace if they are clogged

– Use a fuel injector cleaning kit. Disconnect the fuel pump from the injectors and pressure regulator (if necessary); connect the cleaner to the fuel port; Remove the fuel tank cap to avoid pressure build-up; Start and let the vehicle run until all cleaning solution is used and the engine stops. Remember to reconnect everything again before running the engine.

– Fuel injectors should be cleaned every 30,000 miles (48,000km) of travel

– If the injector is too damaged, the user may have to completely replace it. This should be done by experts in automotive engineering
