11 Reasons for Your Car to Not Start after You Turn It off
You may assume several things when you come across this issue. However, you need to know the actual reasons behind this.
So, we have got here the main 11 reasons for this. Take a look now.
Empty Gas Tank
An empty gas tank is one of the most common reasons for your car not starting. This basically happens when there is very less fuel in the tank.
Note that your car tank has to have enough fuel to run your car. With less fuel, your engine may just start.
However, your car would only be able to run with that if your engine starts for a while.
Your engine needs a combination of spark, enough fuel, and compression if you want to run your car smoothly.
Some people think it’s okay to run one’s car with low fuel or until it finishes off. But this is a very wrong practice.
In fact, this can seriously deteriorate the overall performance of your car.
This is because your car’s fuel filter will be impacted due to this, along with the engine!
The solution is pretty simple, as you don’t have to do anything complicated. To get this resolved, you have to refuel your car’s tank.
Make sure you fill up the whole tank before rerunning your car. Once you refuel your car, let it rest for a while (10 to 12 minutes will be fine).
When you start your car again, try to go slow for the first few minutes. You can gradually increase the speed afterward.
Experts’ Note: You should always check your fuel signal. This means you must ensure your car’s fuel doesn’t go low.
Clogged Fuel Filter
A clogged fuel filter is another reason for your car not to start after turning off. This means your fuel filter has less space for its fuel to pass on.
As a result, your engine fails to work properly at times. Thus, you cannot start your car right if you turn it off.
This mainly happens when the dirt is clogged in your car’s pipeline with time. And this is nothing but a common thing for automobile users. Remember that it occurs mostly if you go for long rides very often.
You need to change the gasoline filter to get out of this issue. Remember that with a journey of around 20000 km, you must replace your old filter.
Or else the pipeline would start getting clogged with dirt. You may want to wash it off, but that may not be feasible.
The car’s starter enables the engine’s crankshaft to work when you ignite the engine. So, if it is faulty, you can’t start your car.
A faulty starter occurs due to gearing issues. This often occurs when a driver starts the car with its headlight turned on.
Rough usage of gears while shifting could also result in this issue.
If you can reach out to the car jack, try to hit the starter motor. Do it use the tire iron.
Sometimes electrical contacts might get caught and need to be knocked loose.
However, if this does not come in handy, you must take the next step. For a faulty starter, you mostly need help fixing the current one.
That means you have to get a new starter to normalize the processing of your car.
A faulty alternator mainly converts chemical energy into electrical energy to replenish the battery. As a result, the car engine functions properly.
However, an alternator can also just mess up all these. If you have a faulty alternator in your car, it won’t start.
This happens due to a problematic generator that fails to charge the battery properly.
Moreover, faulty belts and pulleys might stop the generator from functioning properly. As a result, the alternator of your car becomes faulty!
For this, you should look at the belts and pulleys first. If you can fix that, go ahead. However, for deeper issues, you may need professional help.
A common problem for your car not starting is the wiring problem. This is basically a problem with the fuse box of your car.
The fuse box mainly malfunctions due to dirt clogs or insect interference. Often you may notice a nest of insects beneath the fuse box, resulting in issues starting the car.
Get to your fuse box and check if there is any build-up around that. There is a nest or dirt build-up there.
If you see anything like that, clean it off right away. However, ensure your car engine is turned off and carefully clean it.
Yet, if you see any wiring misarrangement, you may fix it. But if you don’t have the expertise, seek professional help.
People often forget to check the condition of the car’s battery. However, this is actually one of the most crucial things for maintenance.
A car may only partially stop running with a faulty battery. So, you need to address the symptoms of this.
One of the main symptoms is the car not starting right after turning off. This happens when there is a significant drop in electromagnetism, for which your car won’t start right after turning off.
For this, you may actually want to replace the battery. However, you should check your battery before you replace it.
Take an ammeter to see if your battery is actually bad or just having issues. Sometimes the battery is overheated, which needs to cool down.
However, if that’s not the case, replace it. Although many people do this in a garage, you can do it alone.
Just remove the battery and take it out. As the battery is heavy, you may want someone’s assistance for the moment.
Other than that, you can replace the old battery yourself.
A car immobilizer basically prevents your car from getting started with a fake or inappropriate key. As a result, it is like a barricade to your car to get started.
If this is fixed, you may need to start your car even with the right key. This is nothing but an internal and mechanical issue with your car immobilizer.
Tap on the start button while pushing the fob against the start button. In case your model doesn’t have a start button, you may hold the key fob.
This key is around the ignition switch. You would also have to turn the key at the same time.
Although this is common today, it is not negligible. After a long journey, we noticed our engine was hot at times.
Due to this, the engine fails to start working properly right after that. This happens mainly when you run your car for a long time without a break.
As a result, you may see your car not starting after turning it off.
If your car’s engine is overheated, stop the car right away. Make sure you let your car rest for at least 30 minutes, if not more.
Open the bonnet of your car and let some air pass across and through it. Once you understand your car’s engine is cooled enough, you may start your car again.
One thing you must remember is to take breaks on a long journey. Remember that everything needs rest, whether it’s a human or a machine.
It is not always the battery or engine when your car doesn’t start. This can also be due to a faulty ignition switch.
Yes, a faulty ignition switch would let your car not start after you turn it off. An ignition switch may be faulty due to various reasons.
However, this mainly happens due to temperature imbalances, worn out, and broken springs.
If you have a faulty ignition switch, you can first assess the degree of the problem. See if it starts working after giving it a few tries.
Moreover, if you have a spare or imitable key, try working the switch. If you are lucky enough, you may see the switch rotates.
But, if that’s not the case, you would have to call a professional for this.
A timing belt ensures the proper functioning of the camshaft with the crankshaft. If this is faulty, there would be no synchronization of the camshaft with the crankshaft.
As a result, your car would not start off. This mainly happens when there is oil and dirt clogged around it.
Moreover, insects or rats may also interfere with these functions at times.
The first thing you need to do is look for any dirt build-up or any insect interference. If you see any, make sure to clean it off.
However, you may have to oil the timing belt if everything runs smoothly. Yes, sometimes all a timing belt of your car may need is lubrication.
When you oil this, be very slow and steady to not spill over any around this.
Faulty Spark Plug
The spark plug in your car enables its combustion while starting the car. You can’t start your car if the spark plug is bad.
So, you may have a faulty spark plug due to it being overheated. This turns bad for a bad cooling system and improper ignitions like pre-ignition.
You actually can only do a little about a bad spark plug. Therefore, you would have to seek professional help for this.
So, these are the 11 main causes of your car not starting right after you turn it off!
