4 Reasons Why Engines Stall

If your car stalls, it means your engine has stopped working, which can be due to various reasons. Sometimes it can be something as simple as not getting enough air, while other times, it can be a more complex issue like a problem with the fuel system. 

Your engine can stall at any point. It could be shortly after you’ve started it, or it could be while you’re driving. If your engine stalls, don’t be terrified. You can try to get it going again or call for roadside assistance. Here are four common reasons why engines stall.

1. Inadequate air supply

One reason why engines stall is because they’re not getting enough air. This is usually caused by a problem with the air filter or the intake system. The air filter might be dirty, or there could be something blocking the airflow to the engine. 

The air filter is designed to remove contaminants such as dust, dirt, leaves, pollen, or any form of debris. It will often get clogged after a while, which means your engine will receive inadequate airflow and stall. To prevent this, ensure you regularly check the air filter to your Detroit 60 Series Engineand replace it when necessary.

2. Fuel system issues

There are several fuel system-related issues that could cause your engine to stall. The first is a faulty fuel pump. If your fuel pump isn’t working properly, your engine won’t get the fuel it needs to run, and it will eventually stall. A faulty relay or fuse often causes this, so to prevent it, ensure you check your owner’s manual to see where these are located and how to replace them. 

The other fuel system-related issue is a clogged fuel filter. A clogged fuel filter will restrict fuel flow to the engine and cause it to stall. Clean or replace your air filter if you haven’t in a while, to prevent this from happening.

3. Empty fuel tank

If you run out of fuel, your engine will stall. This seems like a no-brainer, but it’s worth mentioning since it’s a common problem. You can know that this is the cause of your engine stalling if your low fuel warning light has been on for a while. Make sure you keep your tank at least half full to avoid this issue. The quality of fuel that goes into your car can also determine how well your engine functions. 

Ensure that the fuel that goes into your car has a rich mixture and is of high quality so as not to damage the engine. If the mixture is inadequate, it will cause cold or intermittent stalling, which can be really annoying when driving. If you use bad fuel, it can clog up your fuel injectors and prevent them from working properly.

4. Bad ignition system

A faulty ignition system is another major cause of a stalled engine. If your ignition system is having issues, it can cause your engine to stall. The most common problem is a bad spark plug. If the spark plugs are fouled or damaged, they can’t create the spark needed to ignite the fuel in the cylinders. This will cause your engine to stall. 

You should replace your spark plugs every 30,000 miles or so to avoid this problem. Another ignition system-related issue is a bad ignition coil. The ignition coil produces the high voltage needed to fire the spark plugs. If it’s damaged, your engine will stall. Check your owner’s manual for more information on how to replace these parts.

Engines stall for many reasons, but these are some of the most common ones. Most of these issues can be avoided by regularly maintaining your car and its engine. Be sure to regularly check your air filter, fuel system, and ignition system to avoid any problems. If your engine does stall, don’t panic. Check these things first and see if you can get it running again. With a little bit of knowledge and effort, you should be able to fix some of the easier problems yourself without taking it to a mechanic. However, if the issue is complicated or if the problem persists, it’s best to take it to a professional to avoid further damage.
