Thinking of doing a Hyundai Elantra fuel pump reset?
But first things first – why do you need to have it done, anyway? And most importantly, what are the benefits of doing a fuel pump reset?
It is worth noting that when work is done on your old fuel pump such as getting it replaced, there are some issues likely to come along when not performed the right way.
For instance, there are some mechanics who discover that the vehicle fails to start after a fuel pump replacement. No matter how many times you crank it, the car simply will not start.
Why does this happen?
Find out what exactly is a fuel pump reset, why it is important, and how to get it done in your Hyundai Elantra.
Hyundai Elantra Fuel Pump Reset
When your vehicle has a shut-off switch to the fuel pump, this cuts off power to your switch. It is designed in such a way that prevents damage during a rollover or an accident. This is why a reset to the fuel pump needs to be done.
But in some vehicles such as the Hyundai Elantra, it may be not so easy to find just where this fuel pump switch is. Once you find it, though, the reset should be a seamless and quick task to do. It is just a matter of finding the switch and doing the reset right.
This issue with starting the engine may happen when you pass over a speed bumper, pothole, or when you have gone through a car accident. The quickest and simplest solution to this issue is by pushing your vehicle’s reset button, which is found on your fuel switch. Since the impact activated the switch, it needs to be reset to be able to start your engine once more.
What may seem like a simple task, however, is made complicated when it comes to finding the location of your fuel pump switch.
This switch offers a security function to cut off fuel supply when there is an accident or a car crash. When your vehicle goes into a sudden stop, the switch is activated and shuts the supply of fuel off.
But before you push the button to the shut off switch, you need to keep important things in mind to prevent damage to your vehicle. Moreover, you need to inspect for other possible problems that may be preventing your engine from starting.
What To Do before Doing A Fuel Pump Reset
In case you are uncertain if the issue is caused by the fuel pump switch getting activated, you need to conduct some tests first.
For instance, make sure that the battery is working and charged. You also need to make sure that the fuel pump relay is still in its place and is in good working condition. The wiring and connector should also be secure and not loose.
Next, inspect the fuse for your fuel injector, as well as the fuse for your electric fuel pump.
Make sure the fuel filter is not clogged. One possible reason why your vehicle is not starting up is when there is debris or buildup that affects the fuel pump’s performance.
And lastly, check for leaks in your fuel supply. A low fuel pressure is often the issue when there is a leak.
Resetting The Fuel Pump Cut Off Switch
Just like your home’s electrical circuit breaker, you should be able to reset your fuel pump cut off switch with a push of the button.
Fuel injection vehicles nowadays come with a cut off switch for the fuel that stops the car from starting after a collision. This stops the fuel from getting pumped that can cause further issues.
When it comes to the Hyundai Elantra, you will need to remove your fuel cap, then check if there is a humming noise for about 2 to 3 seconds. In case you do not hear any sound, the fuel pump may have been burned up or the fuel pump relay’s fuse may have been blown. Another possible reason behind not hearing any sound is the relay popping even before getting this burned up.
Thus, you will need to inspect the fuel pump fuse further in your engine compartment fuse box. Swap out your fuel pump relay with a different relay in your same fuse box engine compartment.
In the Hyundai Elantra, the fuel cut off feature is different from other vehicles. For instance, there is no fuel reset button or shut off switch. Instead, the emergency fuel cut off is located in the airbag control module. When activated due to an accident, the airbags inflate and shuts off the fuel.
Since there is no switch, all you need to do is to fix your airbag system after being deployed. This should correct the issue with your fuel.
Once you have successfully addressed the airbag system controls, then this should resume the fuel pump’s function and you should be able to start your engine.
A fuel pump cut off switch is designed to ensure your safety in the event of an accident by preventing fuel from being pumped. Hence, your engine will not be able to start once the switch is activated because of an abrupt stop due to an accident such as a collision.
In some vehicles, you only need to push a button to reset this component, so you can start the engine. However, this is not the same situation with a Hyundai Elantra. The fuel cut off is in the airbag system, which is activated once the airbags are deployed. Thus, you need to work on the airbag system control module, so you can address the problem with the fuel.
It may seem a bit more complex as it is a different system from other vehicles. Yet, a quick visit to the mechanic should help you out or check your owner’s manual to perform a fuel pump reset right.
