If you’re driving a Chevy and your fuel pump suddenly stops working, it could be due to the fuel pump shut-off switch. This safety feature prevents fuel from flowing after an accident or sudden impact. But where is this reset switch located, and how do you reset it? In this article, we'll walk you through everything you need to know, step by step, so you can get your Chevy up and running again.
What is a Fuel Pump Shut-Off Switch?
The fuel pump shut-off switch is a critical safety feature in many modern vehicles, including Chevy models. Its primary purpose is to stop the fuel pump from operating in the event of a collision or other significant impact. This can help prevent fuel leaks and reduce the risk of fire.
The fuel pump shut-off switch is activated when the vehicle detects an accident or sudden impact, which will cut off power to the fuel pump. It's essentially a way to avoid potential dangers when the vehicle is involved in an accident, ensuring that fuel doesn't continue to flow and potentially cause a fire. Once the switch is triggered, it needs to be reset before the vehicle can start again.
How Does the Fuel Pump Shut-Off Switch Work?
The fuel pump shut-off switch works by interrupting the electrical circuit that powers the fuel pump. It's activated by the vehicle's impact sensors or a sudden jolt, often caused by an accident. When triggered, the switch will stop the flow of electricity to the fuel pump, effectively cutting off fuel delivery to the engine.
Once the switch is triggered, you won't be able to start the engine. However, there's a simple reset process that can get your Chevy running again.
Locating the Fuel Pump Shut-Off Switch in a Chevy
The exact location of the fuel pump shut-off switch can vary depending on the make and model of your Chevy. However, there are a few general locations where you can typically find it. Knowing where to look can save you time and frustration when trying to reset the switch.
Common Locations of the Fuel Pump Shut-Off Switch
In many Chevy vehicles, the fuel pump shut-off switch is located in one of the following areas:
- Behind the glove box: In some Chevys, the switch is located behind the glove box, which is often easy to access. You may need to remove the glove box to reach the switch.
- Near the driver’s seat: On certain models, the switch can be found underneath the driver's seat or near the lower part of the dashboard, often near the floor.
- In the trunk: For some Chevy models, the fuel pump shut-off switch is located in the trunk area. You may need to lift the carpeting or trim panel to find it.
- Under the hood: Occasionally, the switch might be located under the hood of the vehicle. This location is typically found in older models or specific configurations.
Before you start looking for the switch, it's a good idea to consult the owner's manual for your specific Chevy model. The manual will often provide detailed information on where to find the switch in your car.
Tips for Finding the Switch Quickly
If you don't want to spend too much time searching, here are some tips to help you find the fuel pump shut-off switch quickly:

If you're still unable to locate the switch, it's always best to reach out to a mechanic or a Chevy dealership for guidance.
How to Reset the Fuel Pump Shut-Off Switch in a Chevy
Once you've located the fuel pump shut-off switch, the next step is to reset it. Don't worry; the process is simple and can usually be done without any tools. Here's a step-by-step guide to help you reset the switch and get your Chevy back on the road.
Step 1: Locate the Reset Button
As mentioned earlier, the fuel pump shut-off switch will typically have a reset button. It's often red or brightly colored, so it should be easy to spot once you've found the switch. The button will be in a pressed-in position, which indicates that the switch has been activated.
Step 2: Press the Reset Button
To reset the switch, simply press the reset button. You'll usually hear a click, indicating that the switch has been reset. In some vehicles, you may need to hold the button for a few seconds to ensure it's properly reset.
Step 3: Turn the Key to the "On" Position
Once the reset button has been pressed, turn the key in the ignition to the "On" position (without starting the engine). This will allow the fuel pump to receive power and ensure that the system is properly reset. Wait a few seconds for the fuel pump to prime before attempting to start the engine.
Step 4: Start the Engine
Finally, try starting the engine. If the reset was successful, the engine should start normally, and you should be able to drive your Chevy without any issues. If the vehicle doesn't start, it could indicate that there's another issue with the fuel system, and you may need to seek professional help.
What to Do If the Reset Doesn’t Work
If the reset button doesn't solve the problem, it's possible that the fuel pump shut-off switch was not the issue. In such cases, it's essential to check the fuel pump and other components of the fuel system. It could be a malfunctioning fuel pump or a different electrical issue.
If you're unsure about the problem, it's always a good idea to have a mechanic perform a diagnostic check to identify the root cause.
Preventing Issues with the Fuel Pump Shut-Off Switch
While the fuel pump shut-off switch is a helpful safety feature, it's also important to take care of it to prevent issues. Here are a few tips to keep your fuel system and shut-off switch in top condition.
Regular Vehicle Maintenance
Keeping up with regular vehicle maintenance is one of the best ways to avoid problems with your fuel pump and its shut-off switch. Make sure to:
