How to rule out this reason? If you don’t find any blown fuses, or the problem persists even after replacing the blown fuse, the issue might be with other electrical or mechanical components. Open the fuse box, and check if any fuses are blown. How to be sure if this is the reason? Go through the owner’s manual and find out the location of the fuse box. The fuse can melt due to excessive heat and can cause electrical issues, and in turn, cause starting problems. In rare cases, a blown fuse can cause engine start problems. In this case, the problem might be with some other components. How to rule out this reason? There will be no strange noise, or you may hear the cranking noise if the starter motor is in good condition. Unfortunately, you cannot fix the problem yourself, as the starter motor is a complex component, and you will need an expert mechanic to rectify the issue. How to be sure if this is the reason? If there is a fault in the starter motor, you may hear a clicking noise when you turn on the ignition. If it works, the problem is not with the key fob.Īs the name indicates, a starter motor is responsible for cranking the engine and firing it up. How to rule out this reason? You can try locking and unlocking the car via the key fob's buttons. If the key fob is not working due to a dead battery, then the engine start button will not work. The engine will start only if the push-button receives a signal from the key fob. How to be sure if this is the reason? If the engine doesn’t start when you press the ‘START’ button, the problem might be with the key fob. If you have a car with a push-button start system, a faulty key fob may cause engine start problems. In this case, the starter motor may be broken, or there may be some other issue. How to rule out this reason? If you hear a clicking or strange noise when you start the car, the ignition switch works properly. Note that the lights and the horn may still work because there are separate wiring harnesses for the starter motor and other electrical components. You may not hear any clicking or clunking noise when you start the car. How to be sure if this is the reason? If the switch is at fault, then the starter motor will not receive power, and it will not crank the engine when you turn the ignition switch on. The ignition switch carries battery power to the electrical components, such as the starter motor. How to rule out this reason? If the interior and exterior lights are not flickering and there are no strange noises when starting the engine, the alternator may be working fine.Ī faulty ignition switch is one reason for the car not starting. You may also see the battery warning sign on the dashboard, which means that the battery is not charging. A bad alternator will not charge the battery, and hence, the engine will stall. How to be sure if this is the reason? If the car starts and stalls immediately or the dashboard/interior lights are dim, the alternator could be at fault. It might be the battery or the wiring connections.Ī broken alternator can also stop the engine from starting. How to rule out this reason? If there is no rusting/dirt accumulated on the terminals and are properly secured, the problem may not be related to the terminals. If the terminals are loose or there is rusting or dirt accumulated, then the electrical components will not receive power from the battery. How to be sure if this is the reason? Your car will not start if the battery terminals or connection is bad. It is an uncommon problem, but it might happen. If the headlights, horn and dashboard/interior lights are working properly, you can rule out the possibility of a dead battery. How to rule out this reason? If the electrical components of the car are working correctly, the battery is not the culprit. But, again, if none of the electrical components works, the car battery is dead. You can also try switching on the headlights and honking the horn to determine whether the battery has gone kaput. How to be sure if this is the reason? If you don’t see the dashboard lights and hear the cranking noise when you turn on the ignition, the battery may be dead. It is one of the most common reasons for car self-start problems. Below are some of the common reasons why your car is not starting upon switching on the ignition. It could be a minor glitch in the battery terminals, a dead battery, a defective ignition switch and so on.Ĭar starting problems are mainly related to the battery, car self-start system or fuel lines. It doesn’t necessarily mean that there is some major problem with the car. If your car does not start when you turn on the ignition, there might be several reasons behind it.
