Did your car stall or lose power while you were driving it? This can be quite a frightening situation when it happens, so to be sure it doesn’t happen again, lets identify why your car could be stalling. There are a few reasons a car could stall out, so we will go over those reasons and some possible solutions for each.

Why is my Car Stalling?

Inadequate Fuel Pressure

Have you noticed that your vehicle only stalls going up-hill? On an incline (or decline), your fuel has a harder time getting to the engine compartment. It requires adequate pressure to move fuel from the tank and into the combustion engine when gravity is working against it. Luckily, this is a fairly easy fix for your local Gaithersburg auto mechanic.

Bad Spark Plugs

Sometimes, your spark plugs will go bad, and luckily this is a simple fix—replace the spark plugs. You can tell if your spark plugs have gone bad because it is difficult to start the vehicle, and the engine miss-fires. It is this miss-firing which could potentially lead to the engine stalling.

Fuel Pump

Your vehicle’s fuel pump brings gas into the engine. When this component is broken or even just working intermittently it can cause the engine to stall out. When this happens, you’ll need to replace the fuel pump itself. Sadly if the fuel pump was the issue you’ll probably need to have your vehicle towed to the repair shop as it will probably not start.

Moisture in the Gas Tank

Your engine runs on gasoline, and if there is any substance mixed in with that gasoline it can disrupt the efficient burning of this fuel source. One of the more common contaminants in gasoline is water. If your vehicle started stalling after your most recent fill-up, it could be because of excess moisture in the gas tank. The fix here is to drain the gas tank of the bad gas and replace it, but first visit your local Gaithersburg mechanic and get confirmation that this is the real issue.

Weak Battery

Most commonly we associate a battery issue with the inability to even start your vehicle. The truth is, if your battery is going bad or has corroded terminals, it could lead to your engine stalling. When you have a weak battery, your alternator will have to work harder to supply electrical power to your vehicle. This added stress leads to your vehicle stalling out. If you have a voltmeter you can check to see if this is the case, if not you’ll have to bring it into a local Gaithersburg auto service for help.

Ultimately, there are a wide variety of reasons your engine will stall. When this happens, it is a sign that you need to bring your vehicle into your trusted Gaithersburg auto mechanic right away to avoid any further issues.
