Silverado is one of the most versatile and durable vehicles on the market. There is no doubt about that. The wide base of fan following that the brand has speaks loads for its quality.
But, like all of the top-quality products in the world, the Chevy Silverado too sometimes faces some malfunctions. Luckily, none of these malfunctions are too severe and can often be fixed very easily.
A common problem that you might face with your Chevy Silverado is the engine still running after you take the key off. Now, what might be causing this?
If your Chevy Silverado stays running with key off, the first thing that you need to do is get it checked by the mechanic. Your technician will likely look for any fuses that have been installed into the F31UA and the F26UA.
I will be discussing why the issue occurs in-depth down below.
Why Is My Chevy Silverado Still Running With The Key Off?
Wondering how your Chevy Silverado is still turned on even though the key is off? Usually, the root cause is in the fuse or the ignition. But not to worry, these issues can be fixed quite easily.
While these issues might not show up early on in the vehicle, vehicles that have been used for quite some time now can have the problem. It is nothing serious, and won’t cause you too much trouble. The issue can be fixed at home if you know your car well.
Even if you take the vehicle to the mechanic, it won’t cost you too much money if they get the issue fixed.
Fuse Causing Issue In Ignition
One of the main reasons why the Chevy Silverado faces this kind of issue with the engine is because of an issue with the fuse.
When you install a fuse in the f26UA or the f31UA there is a possibility that it causes some malfunction in the performance of the vehicle and causes the Chevy Silverado to stay on even when the key is taken out.
You will notice that the two fuse locations are kept empty when the vehicle arrives at you first from the factory. This is like that for a reason. It is better to keep it empty. So if you have installed fuses, taking them out will make sure that the ignition turns off properly.
Sometimes, you can program the Chevy Silverado key fob to turn your car on. The key fob can also be used to open the door. But, sometimes Chevy Silverado key fobs do not perform well.
If the key fob that you have right now isn’t working, you can easily get a replacement such as the GM Genuine Parts 22936098 4 Button Keyless Entry Remote Key Fob.
You can also use a screwdriver such as the Amazon Basics 51-Piece Precision Screwdriver Bit Set to open the doors if the key fob is not working properly.
Ignition Switch And Power Relay Problems
Another reason why the engine might continue to run as it did before can be because of an electrical issue. There might be some malfunction in the ignition switch or even in the power relay.
The right thing to do at a moment as such is to take the vehicle to a mechanic. They will be able to identify the issue properly. Depending on the severity of the issue you might have to either get it fixed or get the electrical ignition switch or the power relay replaced.
Dieseling Issue
Sometimes, the engine can still keep on running even when the key is out due to dieseling. This is something that occurs when there is residue in the engine combustion chamber. The residue can sometimes get hot enough to light up any of the remaining fuel that resides in the engine.
The process is quite similar to how diesel engines ignite fuel. But, since the Chevy Silverado has modern fuel-injected parts, there is a very low possibility of this occurring.
Even then, if you are sure that this is the reason why your Chevy Silverado remains turned on even when the key is off, you should take the vehicle to the mechanic and they will fix it with a few minor adjustments.
