7 Common Reasons Your Car Won’t Start
If you’re a long-time car owner, chances are you’ve run into one of the most frustrating problems that arise from time to time: your car won’t start. Nothing is more defeating than getting ready to start your day, getting in your car, turning the key in the ignition switch, and hearing that all-familiar sound of your car refusing to start—or worse, no sound.
We know how much this can completely ruin your day and derail your plans, which is why in this blog post, Amarz Auto Service will discuss seven common reasons why your car won’t start and how to fix them. We will get you back on the road as quickly as possible!
What would cause my car to suddenly not start?
Whether you are running late for work, or planning a weekend getaway, a car that won’t start can quickly turn your plans upside down. There are several factors that can lead to a car not starting, ranging from simple issues like a dead battery or a faulty starter motor, to more complex problems such as a malfunctioning fuel system or ignition system.
Dead Car Battery
A dead battery is the most common reason a car won’t start. Factors like old age, leaving your lights on overnight, or a faulty alternator can completely consume the energy inside your battery. Remember, no matter the brand or type, they all have a set lifespan, and while this problem is frustrating, it happens to everyone at some point. Check if your battery is dead by turning on your headlights. If they are dim or not working, you have a dead battery in your hands. To fix this issue, jump-start your car or replace it entirely.
Bad Alternator
The alternator is the part of the vehicle responsible for charging the battery while the engine is running. If the alternator is damaged, missing, or faulty, your battery won’t receive any power, so your car won’t start. Although frustrating, the easiest fix is replacing your alternator altogether.
Faulty Starter
If your battery or its components are not the culprits, a faulty starter could be the issue. A starter is a rotating device that initiates the engine’s operation. When you turn the key, the starter turns and starts the engine. If your starter is not working, your engine won’t be able to start, and you’ll have a dead car in your hands. To fix this, replace the starter with the appropriate one for your car’s make and model.
Bad Ignition Switch
The ignition switch sets the starter in motion when you rotate your key. This small vehicle part sends power to the starter, so if the ignition switch is faulty, the starter won’t receive power, and your car won’t start. To fix this issue, you’ll need to replace it with a new one.
Empty Gas Tank
Your vehicle needs gas or fuel to run, so checking your gas tank should be one of the first steps, unless your car runs on electricity like modern-day eco-friendly vehicles. Many people forget to check their gas levels before starting their car and are in for a surprise when they wake up one morning. Their car won’t start because they forgot to refuel at the gas station. Though the answer is obvious, refill it if you find yourself with an empty tank.
Clogged Fuel Filter
The fuel filter removes impurities from the fuel before it enters the engine. If it’s clogged, fuel won’t be able to flow correctly, and your car won’t start. This can even lead to other problems like poor gas mileage. To fix this issue, you’ll need to replace the fuel filter, but car owners need to know that a fuel filter should be replaced every 30,000 miles, give or take.
Old or Dirty Spark Plugs
Spark plugs deliver electric current from the ignition system to your engine. It supplies a spark that ignites with air and fuel and creates a small catalyst explosion that produces the power to start your car. If they are dirty, old, or have become defective, it can lead to engine troubles like your car not starting. The simplest solution is to replace them.
Troubleshooting Tips
If you are unfortunate enough to encounter this issue, chances are you will want to figure out what’s wrong. At Amarz Auto Service, we’ll be more than happy to troubleshoot your engine troubles for you, but if you feel more comfortable taking a look yourself first, here are some tips on what to look out for:
Check Engine Light
If your check engine light is on, it could be a sign of a problem with your car’s engine. Your car’s computer system could be preventing it from starting to avoid further damage.
Check Your Car Battery
Check again if your engine turns over, identify the sounds you hear when turning the key, or pop the hood open and check the wiring to make sure there are no loose cables that might be messing with your power. If your battery is still under warranty, chances are you will get a free replacement.
Check Your Fuel Tank
It might seem silly to mention this problem again, but a car won’t run with an empty tank. Your fuel meter may be busted, and you’ve been running on fumes all this time, so it’s always a good idea to check your gas levels first before jumping to another conclusion.
Take Your Car for an Inspection
