The car died while driving and won't start: causes and solutions • Road Sumo (2023)

If you are a common person, you will be scared when your car stops suddenly while you are driving on the highway or in heavy traffic. This happens to almost all drivers. This article will discuss what happens if your car dies while driving and won't start: causes and solutions.

If your car suddenly stops and won't start, the alternator may not be working, or the problem may be with the battery. These are just two of the common reasons for this problem. Other parts of the car can cause the car to stall if they don't work.

A car is made up of many parts that must work well together to run smoothly. These parts are grouped into separate systems. If one of these parts and systems is not working properly, it will affect the performance of your vehicle. You can even make the engine stall and the car stop.

Read on to learn more about why your car shuts off while driving, the various reasons why this happens, and how you can diagnose and fix the problem.

Car died while driving and won't start

If your car stalls while driving, it could be caused by one of two things: the alternator is not working, or maybe the battery is not working. Other parts of your car can also cause you to stall.

These auto parts are grouped into different systems to make your car work. If any of these parts and systems malfunction, your car's performance will suffer. It can even cause your engine to stall which causes your car to stall.

But do not worry. Every car problem has a solution. Regardless of what is causing the engine to stall, you need to diagnose the problem and there will be a corresponding solution for that particular problem. The rest of this article will discuss the causes and solutions for this problem:

1. Defective fuel pump

Provides fuel from the tank to the engine.

A fuel pump failure is a common reason for a car to stall when stopped or slowing down. The function of this pump is to supply fuel from the tank to the engine. Fuel is needed inside the combustion chamber for the combustion process.

The engine will stop and the car will stop.

Fuel must be supplied to the engine cylinders at the correct pressure level and correct flow rate. If the fuel is not supplied under proper conditions, the engine will stall and your car will stall. In addition, the fuel flow also depends on the condition of the fuel filter.

Replace faulty fuel pump

If a faulty fuel pump is causing your car to stall, you need to replace it. The best person to solve this problem is a qualified auto mechanic. He needs to take his car to the nearest auto repair shop to have this problem fixed.

2. There is no fuel left in the tank

This is the simplest reason why your car shuts off while driving and the Check Engine Light does not come on.

Could not verify the amount of fuel in the tank

Many drivers face this problem because they don't check the amount of fuel in their tanks before driving. Or maybe the fuel gauge is not working and they can't check the level of gasoline in their tanks.

fill up your gas tank

You should check the fuel level in the tank before driving, especially if the fuel gauge is faulty. The only solution to this problem is to buy fuel at the gas station and fill the tank of the car. And if the fuel gauge doesn't work, have it replaced by a qualified mechanic.

3. The fuel filter is clogged

Clogged fuel filter reduces fuel flow

If the fuel filter is already clogged with dirt and debris, it will reduce the flow of fuel that is pumped to the cylinders. There will not be enough fuel for the cylinders and the engine will fail. If this is not corrected, the engine will eventually stall.

Indication of this problem

If you press the accelerator pedal and nothing happens, then this is the cause of the problem. This is an indication of a problem in the fuel system. Most likely the fuel filter is clogged. Its job is to filter dirt and debris from the fuel so it doesn't get into the combustion chamber.

Replace the fuel filter every time you do an oil change.

Over time, the fuel filter becomes clogged with dirt and debris. When this happens, various problems will arise. one of them is yoursstopped carwhile driving. To correct this problem, it is a good practice to replace the fuel filter every time you change the oil.

4. Alternator problem

Converts chemical energy from the car battery into electrical energy

The alternator is an essential part of your car as it converts the chemical energy in your car battery into electrical energy so that it can supply electricity to all the electrical components in your car. It also recharges your battery too.

The electrical devices of the car do not work.

So if your alternator is not working, then it will not be able to operate the electrical devices in your car. More importantly, the battery will drain. If your battery dies, your car stalls. There is no way to start the car other than to recharge the battery. If the problem is the alternator, you should repair or replace it.

The battery light on your dash comes on suddenly

You'll know if the alternator is failing if the battery light on the dash comes on suddenly. This indicates that your car will still run for a few minutes and then stop.

Take your car to a qualified auto mechanic

This means that no power or electricity is being supplied to the car. You should take your car to a qualified auto mechanic and have them do the necessary repair or replacement to correct this problem.

5. Bad ignition switch

Connects battery power to the starter motor.

The job of the ignition switch is to connect power from the battery to the starter so it can crank over. As the starter motor turns, it makes contact with the flywheel connected to the engine's crankshaft.

As soon as the crankshaft turns, the car engine starts. So it all starts with the ignition key. If it is faulty, your car will stall. You won't be able to turn it on until you fix the ignition switch.

Worn internal contacts

The ignition key can fail if its internal contacts are already worn. This will result in a loss of voltage due to heat and strong vibrations. The worn ignition switch is typical of older, high mileage vehicles. Again, the necessary solution for this problem is available from your trusted mechanic.

6. Bad Sensors

Most of today's cars are operated by ECUs or Engine Control Units. In simple terms, most cars are now controlled by computers. Your car's ECU uses many sensors to control the many components and functions of your car.

Sensors track the movement of critical car components

These sensors track the movement of critical car components and give commands to the ECU based on the signals the sensors send it. The ECU then sends these signals to your car's actuators, such as the fuel injectors and spark plugs, at certain times and sequences.

Faulty sensors will send incorrect readings to the ECU

If a sensor is faulty, it will send incorrect readings to the ECU regarding the condition of your car. This will result in erroneous commands to the actuators, such as no injector pulse or no spark plug signal.

Your car's performance will be affected and it will eventually stall. Fuel injector problems are best dealt with by competent auto mechanics.

7. Bad battery

Helps alternator maintain correct voltage

Bad battery is also one of the most common reasons why cars won't start. Many drivers assume that the only function of the battery is to start the car. This is not true because it also helps the alternator maintain the correct voltage while the car is running.

Overloaded alternator puts extra strain on car engine

If the battery is bad, the alternator will work harder to maintain the correct voltage your car needs. An overloaded alternator puts extra strain on the car's engine. If this goes on indefinitely, eventually your car will stall. Your car dies while you are driving, but you still have power.

Buy a new battery

You can fix this problem by purchasing a new battery and installing it yourself if you have experience with common tools and knowledge of working with car batteries. This will save labor costs.

Again, what would cause a car to suddenly die while driving? When your car suddenly dies while driving, you need to have your battery or alternator checked. Also, inspect your car's electrical, terminals, connectors, drive belts and fuel systems and check if the fuel filter is clogged.

8. Power consumption caused by air conditioning

Does your car lose power when it's hot outside? If so, the air conditioning system could be draining electricity from your car's power source. In this condition, your car's air conditioner will consume more than its power allowance.

AC is diverting power to cool your cabin

If you're going on a long road trip during the summer, you may find it difficult for your car to pull the weight it previously had no problem pulling.

The engine is probably under stress because the air conditioner is diverting power to cool your cabin. You can even stop your car if there is no more power to share.

Turn off the air conditioning in your car

You can avoid this problem by turning off the air conditioning whenever you feel the engine having a hard time pulling the vehicle. Or, you can have your AC and electrical systems checked by an auto electrician to implement the proper fix.

9. Diesel particulate filter clogged

If your car runs a diesel engine, it will have a diesel particulate filter (DPF). Its function is to remove particulate matter from diesel fuel. Like any filter, it can clog over time. Once locked, your car will switch to "clean mode" to prevent further engine damage.

Suppose you think your car switches to this mode; Limit your driving to a few miles. You should take your car to the nearest repair shop so that it can be checked by a qualified mechanic.

10. Bad fuel injector

Clogged or leaking fuel injectors can occur on high mileage cars. When a car has this problem, it will have trouble accelerating at high RPMs.

If a car has fuel injection problems, it will also manifest problems with the ignition system, combustion chamber failures, or even the smell of fuel in and around the vehicle. These problems can also cause your car to stall. Only a qualified auto mechanic can fix this problem.

How to fix a car that won't start (no noise)

What to do when a car has died while driving and won't start

It is very stressful if youcar dies while on a highway. But she is not scared. There is a way out of this problem:

1. Safety is your first concern

If your car suddenly dies while driving, your first concern is the safety of yourself, your passengers, and other drivers on the road. Keep calm and no one will get hurt.

2. Move your vehicle off the road

Turn on your hazard lights to alert other vehicles behind you and vehicles going from the opposite direction.

Your steering wheel may get stuck, but try to steer your vehicle to the side of the road. And once you're there, set the parking brake so your vehicle doesn't roll.

3. Do a preliminary inspection of your vehicle

Now that your car is safe on the road, do a preliminary check on your vehicle. If the dashboard shows a warning light, it could be a battery problem. Maybe it's not charging. But the alternator could also be the problem.

Inspect the electrical system, terminals and connectors. If the connectors are loose, tighten them. You should also inspect the drive belt if it is already loose or damaged. Replace this belt if it is already damaged.

4. Restart your car again

Try to restart the engine. If it restarts again it could be a problem with a clogged fuel filter. If it doesn't reset after unclogging or even replacing the fuel filter, it could be a weak or faulty fuel pump issue. You have to check the fuel pump and hoses.

The point here is to keep checking until you get to the source of the problem. Do you know that there are many reasons why your car suddenly dies while you are driving? Therefore, you must check all these possible causes until you reach the reason why your car has stopped working.

If your car shuts off while driving and then comes back on after it cools down, it could be a problem with the engine management system or ECU. In this case, it is best to take your car to the nearest auto repair center so that it can be checked by a qualified mechanic.

This is too technical for the average car owner to understand and repair. Ordinary car owners do not have the tools, skills and knowledge to fix these car problems, but reputable auto repair shops have all the tools and manpower to fix them.

What can AAA do if your car won't start?

frequent questions

If you want to know what you can do if your car stops suddenly in traffic, here is more information. These are the answers to the most frequently asked questions on this topic:

Why did my car die while driving and won't start?

There are many reasons why yourthe car stalled while driving and won't start again. It could be a problem with the battery or the alternator. Checking the terminals and connectors will help identify the problem.

What are the other causes of this problem?

It could also be a problem with the fuel pump or fuel injectors. If fuel is not supplied to the combustion chambers, the engine will not be able to turn and the car will stop abruptly.

It could also be a fuel shortage problem. If your car runs out of fuel, you won't be able to start it. A faulty fuel gauge causes this problem. So if you replace an inaccurate fuel gauge, you won't run out of fuel because there is something to tell you that you are low on fuel.

The problem could also be caused by a clogged fuel pump. Even if you have a lot of fuel in the tank but it cannot flow properly to the combustion chambers because the fuel filter is clogged, there will be no combustion. As a result, your car will stall.

What happens if the alternator dies while I'm driving?

If the alternator fails while you are driving, the battery is needed to provide all the electrical power your car needs. But that can't last long. The battery and the alternator work together. The alternator replenishes its juices while you are driving your car.

So if the alternator fails, the battery juices won't get recharged. As you keep driving your car, it will consume the juices left in the battery. When it's all over, the battery will be dead and so will your car.

In Conclusion: Why Your Car Dies And Won't Start Again

If you're driving your car and it suddenly dies and won't start, the alternator may not be working, or it's probably a problem with the battery. These are two of the most common reasons for this problem.

There are other parts of your car that if not working can cause your car engine to stall. These auto parts are grouped into separate systems. If any of these parts or systems fail, it will affect the performance of your car. It will even make it stop if the problem is severe.
