The start-then-die phenomenon is common problem faced by many car drivers once in their lifetime. Here in this article, we will discuss the root cause behind this frustrating problem so that it becomes easy for you deal with the situation.

Bad Fuel Pump

One of the leading causes behind the car start-then-die problem is related to the fuel system in general and the fuel pump in particular because often it is observed that a bad fuel pump is the primary cause behind the starting and then stalling issues faced by the vehicles.

The fuel pump is responsible for delivering pressurized fuel from the fuel tank to the engine of your car which is required for the combustion process. However, when you are driving with a malfunctioning fuel pump under the hood of your car then the engine is not going to get pressurized fuel and this affects the combustion process adversely.

This is when you get to experience start-then-die issues in your car while driving and you are also going to observe that the car sputters at high speeds or you will face difficulty when accelerating. A fuel pressure test performed by a professional mechanic would reveal if the pump is delivering an adequate amount of pressurized fuel to the combustion chambers or not.

Mass Air Flow (MAF) Sensor Failure

There are a host of sensors in your vehicle that are responsible for monitoring the functioning of the vital components and the MAF sensor helps in measuring the amount of air entering the engine and this information is used by the onboard computers to adjust the fuel flow to the engine of your car.

Over the years the MAF sensor can encounter issues with its functioning or get clogged up due to accumulation of dirt & debris and this leads to inaccurate information being passed on to the onboard computers. This often causes too much fuel or too little fuel to flow into the engine leading to various problems including the start-then-die phenomenon.

In addition to the stalling problem, you are also going to encounter rough idling and poor acceleration while driving. Most of the time cleaning the clogged MAF sensor helps in dealing with the problem, however, if the issue persists even after cleaning then you have to replace the sensor.

Faulty Ignition System Components

The ignition system in your car consists of a host of components that play a crucial role in igniting the air-fuel mixture in your combustion chamber. However, issues with any of these parts like the spark plugs, ignition coils, and distributor can lead to your vehicle starting but dying suddenly.

Most of the time it is observed that faulty spark plugs in cars are the main culprit behind the stalling issues as it fails to ignite the air-fuel mixture in the combustion chamber. Moreover, if the ignition coils are worn out then the engine is going to fire initially but will fail to keep the combustion going.

You are also going to notice a drop in the performance of your car due to underlying ignition system issues and the best way to avoid getting caught in this horrible situation is by regularly inspecting and replacing the malfunctioning ignition system components before they start to affect your car eventually.

Blocked Fuel Filter

The fuel filter in your vehicle is responsible for preventing the entry of dirt & debris by filtering the fuel entering the engine. However, over the years, the fuel filter can get clogged with contaminants and this affects the smooth flow of gasoline into the combustion chamber of your car.

That is why it is important to replace the fuel filter of your vehicle as per the manufacturer-recommended maintenance schedule of your car. This is one of the most overlooked maintenance aspects of cars and you must guard against committing this mistake.

Finally

Malfunctions in the ignition switch could adversely affect the performance of an internal combustion engine. Moreover, you might not be able to start the engine of your Volkswagen due to the failure of the ignition switch. So, early warning signs of a failing ignition switch in your vehicle should not be neglected. Please go through this graphical presentation to learn more.
