5 of the most common reasons your car won't start (+ how to fix them)

If your car won't start, don't panic. There are a few things you can do to troubleshoot the problem and get your car up and running again. In this blog post, we will discuss the five most common reasons why cars fail to start and how to fix them. We'll also provide some tips on how to check your car if it doesn't start and what you should look for when trying to troubleshoot the issue. So don't worry - even if your car won't start, we've got you covered!

Dead Battery

The first thing you should do if your car won't start is to check the battery. If the battery is dead, it will need to be replaced. You can usually tell if the battery is dead if the car won't turn over at all or if it makes a clicking noise when you try to start it. If the battery is dead, you'll need to jump-start the car or replace the battery. Most local car shops have delivery options available that can bring you a new car battery with same-day delivery.

Faulty Starter

If the battery isn't the problem, the next most common reason why cars won't start is because of a faulty starter. If the starter is damaged, it can prevent the car from starting. You can usually tell if the starter is damaged if you hear a clicking noise when you turn the key in the ignition. If the starter is damaged, you'll need to replace it. While you can replace the starter yourself, it may be best to call on a professional mechanic to ensure it is properly installed.

Issues with Fuel Pump or Fuel Filter

Another common reason why cars won't start is because of a problem with the fuel system. If there's an issue with the fuel pump or fuel filter, it can prevent the car from getting enough gas to start. You can usually tell if there's a problem with the fuel system if the car starts but then stalls soon after. If there's a problem with the fuel system, you'll need to have it repaired or replaced. The average cost to replace a fuel system can be anywhere from $220 to $1,062 depending on the make and model of your car. 

Bad Spark Plugs

Another possibility is that the car won't start because of an issue with the ignition system. If the spark plugs are dirty or damaged, they may not be able to create a spark and start the car. You can usually tell if the ignition system is the problem if the car starts but then dies soon after. Spark plugs should be replaced every 100,000 miles, so it may be time for a routine replacement if you find that your car is not starting for this reason.

Issues with Transmission

Finally, another common reason why cars won't start is because of a problem with the transmission. You can usually tell if the transmission is the problem if you turn the key and nothing happens - no clicking, no engine turning over, nothing. If the transmission is the problem, you'll need to have a professional mechanic repair it as this will require shop tools and devices to ensure it is properly repaired or replaced.

These are just a few of the most common reasons why cars won't start. If your car is having trouble starting, don't hesitate to take it to a mechanic to have it checked out or schedule an appointment with a Curbee mechanic to have your car inspected. They'll be able to diagnose the problem and provide you with detailed steps on how to get your car running again.
