When you aren’t driving a manual vehicle, when you’re car stalls – it can cause a lot of concern. So what do you do? And how do you fix it? We created a short list of how to troubleshoot a few items yourself:
1. Empty fuel tank.
If your low fuel warning light is on, and it has been on for a while, this is probably the most likely cause.
2. Fuel mixture isn’t adequate.
If your car is stalling when it’s cold or stalling intermittently, your fuel mixture might not be adequate. This usually happens when the mixture of fuel and air isn’t rich enough.
3. Bad fuel pump.
If your fuel pump quits or isn’t working properly, then your engine won’t get the fuel it needs to run, which results in the engine stalling. You won’t be able to restart your car if the fuel pump quits.
4. Bad alternator.
Your alternator is responsible for charging your battery and running many essential functions in your engine. If your alternator quits, your car will quit too. However, there are usually plenty of warning signs of impending alternator failure, including dimmed lights and your battery not charging.
5. Dead battery.
Most of the time, if your battery is dead, you won’t be able to start your car. However, if your battery is going bad, then you may experience stalling due to the alternator being overworked. Before replacing your battery, make sure that a failing alternator isn’t the culprit.
What does it mean when a car stalls when braking?
If your car stalls when braking, then it usually means you have a vacuum hose blockage in the brake booster or a leaking master cylinder. Or you could have a leak in the ABS system. In either case, this can be difficult to track down without professional help.
What causes a car to stall while driving?
There are a large number of reasons why your car might stall while driving. It could be a dead alternator, a bad coolant sensor or lack of fuel, just to name a few. Is your car stalling while accelerating? If so, then it could be a major vacuum leak, clogged fuel filter or a bad fuel pump. If your vehicle is stalling when driving, seek professional help to track down and fix the issue.
How to fix a stalling vehicle
The first step is to make sure that it isn’t a simple issue such as an empty fuel tank or improper clutch application. Once these have been ruled out, you can move onto more complicated reasons. If you know your battery is old and you don’t have any symptoms of alternator failure, then your battery could be the cause.
Other easy fixes include adding injector cleaner if your vehicle stalls on inclines or replacing your air filter if you check it and it looks dirty. Beyond these, most drivers will need professional help to track down the reason for stalling and then get it fixed.
