11 common reasons why your car won't start even on new battery: Car won’t start new battery
Your car won't start even on a new battery
So, you have just installed the new car battery and still your car won’t start even with a new battery, we never really know in life how important anything is until it's gone... And this is particularly true in the case of your car. You use it to take your children to school, drive to work, get groceries, driving around the city, and more. So, when all of a sudden it stops running, it's an incredible pain.
There are a lot of reasons why your car won’t start new battery or even an old one which was working just fine 2 hours ago, but some are more prominent than others.
11 common reasons why your car won't start on new battery or an old working one and some tips to ensure your car stays in top shape are listed below!
1.Empty gas tank.
The problem may not be your new battery, the new battery may be working just fine. Your gas tank may be empty and If this is the reason why your car does not start, you might feel a little foolish, but it happens more often than you might think! It's also easy to forget when driving around all the time that your gas tank needs to be refilled. The answer is easy here... Grab more petrol!
2.New car battery dead.
Maybe your new car battery is dead. A dead battery is always one of the common reasons why your car won’t start even with a new battery. The battery is what the vehicle uses to supply the whole car with electrical power and electrical parts (e.g., lights, radio, etc.). The alternator is the one charging the battery inside the car while the engine is running. You won't be able to start the car or use any electrical components if the battery is not charged enough.
For a number of reasons, your battery might be died:
- Your headlights or dome lights were left on for too long or overnight.
- You have a loose cable
- The water evaporated inside the component, causing poor conductivity.
- The battery's lifespan has expired
Some symptoms that are typical include:
- The electrical components are not working (e.g., the lights, radio, etc.).
- The Car battery light is on.
To know if it is the car battery having a problem, one of the ways to test this is by jump starting the car. If the jump start works, you might be dealing with a dead battery.
3.Battery corrosion.
Corrosion can spell trouble on your battery. To make sure that there is a clean, complete connection, check and clean the battery posts, then try to start your car once again. An employee of the auto store may guide you to the correct items and provide advice on how to clean your battery.
4.Cables problem.
All the time, battery cables go bad. Not only are the connections crusted with corrosion, but the corrosion within the cables will crawl down making them all but useless.
A test known as voltage drop test can always tell us if it is the battery cable which might be the problem. Using the Voltage setting on the multimeter, first of all try to touch the probes to the battery terminals in order to determine the current voltage of the battery. For a fully charged battery, the voltage should be about 12 volts ready to go.
Secondly, we should perform a voltage, drop test of the cables and terminals by touch one probe to the battery post, and then the other probe to the terminal. It should read at zero or near zero. If the reading is any number lower (negative numbers like -0.01, for example), then you’re losing voltage in your cables.

5.Faulty starter.
Your car won’t start on new battery but again the problem might not be your new battery, it may be a starter. A starter which is broken may be the reason your car won’t start even on new battery. A starter is an electrical motor which is connected to the battery of the car. The role of the starter is to set the engine in motion after turning the ignition switch on. When the engine starts and it is in motion, the job of the starter is complete. If the starter is broken, the engine will not crank properly or may not crank at all when you turn the ignition switch on. If you hear a clicking noise when you try to start your vehicle, a broken starter could be the reason why your car isn't starting even on new battery or an old working one.
Some common symptoms include:
- Car not starting when turning the ignition switch on.
- Hearing a loud clicking sound when turning the ignition switch on, but the engine does won’t start.
- Very noisy when trying to turn on your car.
6.Clogged fuel filter.
Car battery dead? Again, the problem might be the fuel filter not your new car battery. The gasoline won't be able to hit the engine if your fuel filter is clogged. This makes it hard to burn the fuel your car needs to get moving. Every 15,000 to 20,000 kilometers, fuel filters should be modified, so consider changing fuel filters next time you get your car serviced.
7.Bad timing belt.
My battery is dead? The problem might be the timing belt and not your new battery, the timing belt ensures at the correct interval that the valves of the engine open and close so that the valves and the pistons never touch. The timing belt in your engine is the most important maintenance product. A failed timing belt can cause catastrophic damage to the engine, requiring replacement of the engine.
8.Broken or cracked distributor cap.
New car battery dead? The role of the distribution cap is to route voltage from the engine’s ignition coil to the spark plugs. When the moisture gets under the cap, it can cause some problems for your car not to start even on that new car battery. Wipe it out with a dry and cloth before reinstalling it. Remember to replace a damaged cap.
9.Bad Alternator.
If the alternator is not good, it will throw a “CHARGE” light on the dashboard, or even trying to show you that you’re not running at 14.3 volts. But that light on the dash or gauge might not be working the way it should.
By using a multimeter, you can test how much voltage the alternator is throwing out. By attaching the probes one to the negative terminal and the other one to the positive terminal of your battery, try to make sure in the engine bay the probe leads are out of the way of any moving parts, and fire the engine up.
The multimeter has to read between 14.2 and 14.7 volts. If the multimeter shows less, the battery isn’t being charged as well as it should. If it shows MORE than 14.7 volts, the alternator is overcharging the battery and it may kill your new battery.
10.Defective ignition switch.
If you have tested the battery and you know that it is working properly, but the car won’t start after the first few tries, the problem might be the ignition switch. Trying to narrow down the cause of your issue by turning on the headlights. The reason to do this is that the car's battery controls the dashboard and the headlights, if the lights turn on but your engine isn't able to start still, then ignition switch is the problem.
11.Bad ignition coil.
Car won’t start new battery? The problem might be the ignition coil. The role of the ignition coil is to transform a battery’s voltage into an electric spark. A broken ignition coil means that there’s no enough juice to start the car. You may need a multimeter to test the strength of the current running through the coil
