One of the biggest questions that most people have is why won’t my car start? The first thing that you should do when your car won’t start is to locate the cause of the problem. It could be anything from a bad battery, or perhaps the ECU (electronic vehicle unit) has a problem. A battery may be one of the first things that should be fixed as if it is not properly maintained it can lead to electrical problems with the rest of the system.
If you have a faulty battery or a bad ECU then the battery cables may be to blame. You should check all the connections to ensure that they are in good order and clean any connectors if necessary. If you find that one connection is faulty then you should replace it immediately. In addition, check the fuel line to ensure that it is not clogged, or leaking fuel which will also affect your car start.
If you have a problem with your battery or the end then the only option available is to have a new one installed. There are several ways you can do this, but in most cases, it is a case of removing the old one and fitting the new one. This can be done by either phoning your local garage or dealer or by doing it yourself by following the below steps.
How to fix it?
In most cases, the first step is to turn off the engine and depress the starter. Once the engine has stopped then disconnect the battery cables. Take note of where the two voltage cables go, they will be white and black. These wires connect the positive and negative leads to the spark plugs.
The next step is to remove the battery cables and get access to the spark plug. Check for any damage, leak, or holes. You need to determine if you need a new ECU or a new battery. You can use a continuity tester to check whether the battery cables are connected correctly or not.
Check the spark plugs
Once you have checked the connection of the battery cables to the spark plugs then you can disconnect the fuel mixture and ignite it. You need to look at the carburetor to see whether it is leaking. Usually, a carburetor will have two holes where the air enters the combustion chamber. You can use a funnel to test whether there is any air leaking in the combustion chamber.
And piston rings
If you have found no leaks then your next step is to check the piston rings and injector lines. A car starter problem can occur if the fuel injector does not work properly. To check the injector lines, you need to open up the fuel pump assembly and look inside the pump housing.
If you can see some black/blue fluid in the fuel tank then it indicates that there is leaking somewhere in the fuel system. Next, you need to check the exhaust port on the exhaust pipe by using an exhale siphon. You need to open the exhaust port and sniff the gas out to see if there are any leaks in the pipe.
If you still have problems after the above test then you need to replace the dead battery cables with a new one. Once you have replaced the dead battery cables then you need to replace the spark plug. Also, replace the carburetor and wires. Check the connections of the fuel pump and the new one using the same method.
Maybe the reason is broken piston rings
Another reason why your car won’t start is worn piston rings. The wear in the piston rings means that the air has no place to go so when it comes into contact with the spark plug, it causes a reaction that causes the spark plug to be burned.
The best way to avoid this problem is to clean the carburetor before using it. Another cause of a car battery not starting is if the starter solenoid is not open. To fix this problem you need to open the starter solenoid and check for any worn parts on the solenoid.
Is your filter cleaned?
One of the best ways to help prevent your car from starting is to change your fuel filter regularly. A dirty fuel filter can stop your vehicle from working and if you notice that the fuel filter is plugged with sediment then you should change it as soon as possible.
Also, change your spark plug, or at least clean the parts connected to it regularly to prevent the risk of having your vehicle stopped due to a spark plug being worn out. If you see your vehicle is running poorly then you may have to replace worn-out spark plugs.
Defective cold start valve
One more cause why my car won’t start is faulty, cold start valve. In a dead battery, the cold start valve does not open properly so that when you press the pedal it doesn’t make any resistance. The problem with this is that the starter uses a large amount of electricity to charge the battery and it uses a small amount of fuel also to keep the battery charged and ready to go.
If you find that the cold start valve is faulty then you will need to take out the spark plugs and check the valve for signs of life. If the valve is damaged then you need to replace the battery. I hope this article helps and provides you with information on why your car won’t start.
