How come my car won't start?

Hopefully you won't ever find yourself in the situation where your car won't start, but if it does, you'll need some help. A qualified technician will need to accurately diagnose and evaluate the problem.



The starter, which turns the engine over so it can start running on its own power, is what produces the brief, repeating chirping sound the engine makes when you turn the key to start your automobile. You want to hear that noise, known as "cranking," since it indicates that your car's starter is working properly. What happens, though, if you hear the engine crank but it just won't start and run on its own? That indicates an issue with the engine itself that's preventing it from getting started. 


A damaged or broken ignition switch can prevent your automobile from starting, much like the starter engine can. If your headlights work but your car won't start, your battery is charged but the starter or ignition isn't working properly.


There are a few options if you believe the issue may be fuel related. Your gasoline line could have frozen if the temperature is low enough, and it would need to be thawed.


Now, even if the gasoline filter partly clogs, your car will still operate. However, you won't be able to start your car if the gasoline filter is entirely blocked. The same thing may occur if corrosion or particles clog the fuel injector nozzle.


Bad sparks plug symptoms are difficult to identify and frequently coexist with problems with other car parts. The easiest way to determine whether you have faulty spark plugs, broken distributor caps, or even a damaged ignition coil is to get your car checked out by a qualified mechanic.


A fading or dead battery frayed or corroded connecting cables, a defective alternator, or a problem with the starter are the common culprits when a vehicle won't start. It might be challenging to tell whether a battery or alternator issue is at hand.



However, the majority of the symptoms are quite similar regardless of whether the issue is caused by a damaged fuel pump, a defective alternator, a blown fuse, or a dead battery. Some of these may even be signs of more serious underlying problems that only specialists can identify.


A timing chain may be used in some vehicles in place of a timing belt. Typically, it outlasts the rubber belt. However, you will still need to call a professional to fix a broken timing chain.


You can notice odd discrepancies in your engine's rpm range, ticking noises from the engine, or your engine not turning over if your timing belt is damaged. If you detect any problems that could be related to your timing belt, don't hesitate to call your technician. Timing belt replacement is a piece of maintenance that should be carried out on a semi-regular basis.

Your automobile won't start most frequently due to a dead battery. The battery is what the vehicle utilizes to power all of its electrical systems and systems inside (lights, radio, etc.). The alternator charges the battery while the car is moving. You won't be able to start the vehicle if the battery is not fully charged.


Despite the fact that most automobiles are fuel-powered, all vehicles need electricity to function. Your engine's starter needs an electrical signal to ignite in order to crank it. Your car's engine won't start if your battery has a problem. Although there are other signs that might point to a dead battery, it is always a good idea to see whether your engine even turns over.


A poor battery is always accompanied by a defective alternator. After the car has started, the alternator keeps the electrical systems working while recharging the battery. You might not necessarily have a faulty battery if your alternator is bad, but you definitely might not have a working one. You should always repair any damaged alternators, so be on the lookout for any warning indications.


Inadequate compression

An engine requires four things in order to start moving forward on its own: air, fuel, compression, and spark. When an engine has low compression, it may be difficult or impossible to start, which indicates that the engine's seals and gaskets may be leaking. In order for the engine to endure the high pressure required for operation, you might need to change parts like new valve seals, new piston rings, or other components.


Fuel Injector Blockages

The engine may not start even if the automobile starts when you turn the key because gasoline may not be reaching it.

Turn the key to the run position while the radio is off and wait two seconds while listening for a buzzing sound. The gasoline pump is priming the injection system at that moment. If there is no sound, either the fuel pump relay is malfunctioning, or the pump is beyond repair.


If your lights turn on when you turn the key in the ignition, it is one of the simplest signs that your starting motor needs repair. Your starting motor may be to blame if you've turned your key all the way and the lights come on, but the engine won't start. Turning your key all the way turns your battery on. Any electrical failure symptoms could potentially be a clue that the starting motor requires repair. A starting motor that has had a blown fuse could overheat and start to smoke if you keep attempting to use it.


Nobody wants to run out of petrol, but if it does happen, there is good news: your automobile is in good shape. Your best option if your tank is empty is to find a gas can, fill it up with the few gallons it needs to start, and drive to a gas station.
