When you try to start your car, and it simply doesn’t turn over, you may begin to panic. After all, being unable to get your car running can seem like the worst-case scenario because of the number of possible scenarios that could explain why it won’t start. Whether your battery has died or you have an issue with your starter or fuel system, there are five common reasons why a car won’t start. Knowing what they are will help you find ways to solve the problem and get back on the road as soon as possible.
Reason 1: Dead Battery
One of the most common reasons a car won’t start is because the battery is dead. If your headlights are dim or you hear a clicking noise when you turn the key, your battery likely needs to be replaced.
Reason 2: Worn-Out Starter
A starter is a small electric motor that turns the engine to start the car. It’s located on the side of the engine block and is usually driven by a long, flat metal rod called a drive gear. If your car has trouble starting, it could be because the starter is worn out. This is especially common in older cars.
Reason 3: Clogged Fuel Filter
A clogged fuel filter can prevent your car from starting because it doesn’t allow enough fuel to reach the engine. Over time, the filter can get clogged with dirt and debris, which can restrict fuel flow and cause your car to stall. You may be able to tell if your fuel filter is clogged, if your car has trouble starting or if it stalls frequently.
Reason 4: Corroded Battery Terminals
When corrosion builds up on the battery terminals, it can prevent electrical current from flowing freely to and from the battery. This can lead to car trouble, including a car that won’t start. Have your mechanic inspect your car’s battery when you bring your vehicle in for service, and clean the terminals if necessary.
Reason 5: Failing Fuel Pump
Another common reason a car won’t start is because the fuel pump has failed. The fuel pump is responsible for delivering fuel to the engine; if it’s not working, the engine can’t run. There are a few signs that your fuel pump may fail, including loss of power while driving, difficulty starting the engine, and strange noises from the engine. If you suspect your fuel pump is failing, it’s essential to have it checked out by a mechanic as soon as possible.
If your car doesn’t start, don’t panic. There’s usually a simple solution that your mechanic will be able to find and repair so that you can get back on the road.
