Does a Chevy Equinox have a fuel pump?
The Short answer: yes. The Chevy Equinox uses an electric fuel pump located inside the fuel tank as part of a pump module that feeds the engine. This article explains where it sits, how it works, common failure signs, and what replacement or maintenance entails.
The Equinox, like most modern GM crossovers, relies on an in-tank electric fuel pump to deliver fuel at the correct pressure to the engine. The pump is typically integrated with the sending unit inside a single module, and it operates within a returnless-style fuel system that uses the engine control module to regulate pressure. Access to the pump varies by model year and trim, and replacement usually involves working with the fuel tank rather than a standalone, externally mounted pump.
Where the fuel pump is and how it works
The fuel pump in most Equinox models is an electric unit mounted inside the fuel tank. It’s part of a larger pump module that also contains the sending unit and a filter screen, drawing fuel from the tank and pushing it through the fuel lines to the engine. In modern designs, the pump helps maintain steady fuel pressure as controlled by the vehicle’s computer, supporting efficient combustion and cold-start performance.
Before listing the main components and their roles, here is a quick overview of what to expect:
- In-tank electric fuel pump module: The pump sits inside the fuel tank and is connected to a sending unit and a filter.
- Sending unit integration: The module also measures fuel level for the fuel gauge and communicates with the SLAVE/ECU as needed.
- Fuel pressure and system design: Many Equinox models use a returnless design where the pump is controlled to maintain appropriate pressure in the fuel rail.
- Accessibility and replacement: Access to the module varies by year and trim and may require removing portions of the rear seat area or the tank top cover; replacement generally involves the pump module as a unit.
Conclusion: The fuel pump’s in-tank location is standard for the Equinox, designed to provide reliable pressure and cooling from the circulating fuel.
Common signs of a failing fuel pump
When the fuel pump begins to fail, several symptoms can appear. The following items describe the most typical indicators you might notice:
- Long crank times or difficulty starting the engine after it sits, especially when hot.
- Engine stalling or sudden loss of power under acceleration or load.
- Reduced engine performance, hesitation, or misfires due to inconsistent fuel delivery.
- Unusual noises from near the fuel tank (often described as a whining or buzzing sound) when the engine is running or the key is in the on position.
- Check Engine Light or fuel-specific trouble codes related to delivery or pressure.
Note: These symptoms can also be caused by related issues such as a faulty fuel pump relay, wiring problems, a clogged fuel filter, or a failing fuel pressure regulator. Proper diagnostic work is essential to confirm the pump as the cause.
Maintenance and replacement considerations
Replacement basics and what to expect
Because the fuel pump is housed inside the tank, replacing it is a more involved job than many external components. If you suspect a failure, basic diagnostics and safe handling are essential. Typical steps in the replacement process include:
- Relieve fuel system pressure and disconnect the battery to prevent sparks.
- Access the pump module. Depending on the year, this may involve removing a rear seating area or accessing a panel in the trunk/floor and then safely supporting or lowering the tank.
- Replace the entire pump module (not just the pump) to ensure a proper seal, sending unit accuracy, and filter integrity.
- Reconnect electrical connectors and fuel lines, then reassemble and test for proper operation and fuel pressure.
Because fuel system work involves flammable liquids and requires precise sealing and electrical safety, many drivers choose a trained technician for this job. Always refer to the specific owner’s manual for model-year–specific procedures and safety guidelines.
Summary
In summary, the Chevy Equinox uses an electric fuel pump located in the fuel tank as part of a modular pump assembly. This design is common across modern GM crossovers and supports reliable fuel delivery with a returnless-style system in many years. If you notice symptoms of fuel delivery problems, pursue proper diagnostic steps or consult a qualified technician to confirm pump health and address any safety concerns during replacement.
How do I find out if my fuel pump is bad?
You can check if a fuel pump is bad by looking for symptoms like difficulty starting, engine sputtering, or a lack of power, and performing diagnostic tests such as using a fuel pressure gauge to measure pressure or spraying starter fluid into the throttle body to see if the engine briefly runs. Listening for the fuel pump's normal humming sound when you turn the key is also a good first step.
Common symptoms of a bad fuel pump
- Difficulty starting: The engine may crank for a long time before starting, or it may not start at all.
- Engine sputtering or shaking: The engine may hesitate or sputter when accelerating, and could shake excessively while idling.
- Loss of power: You might notice a significant drop in power, especially when driving uphill or carrying a heavy load.
- Unusual noises: A whining or humming sound coming from the fuel tank area can indicate an overheating or failing pump.
- Stalling: The engine might stall while driving and, in some cases, may be able to restart after sitting for a few minutes.

Diagnostic tests to perform
- Listen for the fuel pump: Turn the ignition key to the "on" position without starting the engine and listen for a low-pitched humming sound from the gas tank. A working pump will often run for a few seconds to build pressure. If you don't hear anything, there could be a problem.
- Use a fuel pressure gauge: This is the most definitive test. Connect a fuel pressure gauge to the fuel rail (or pressure test port) and compare the reading to the manufacturer's specifications. Low or no pressure indicates a problem with the pump or a blockage.
- Try starter fluid (as a quick check): For a no-start situation, spray a small amount of starter fluid directly into the throttle body and have someone crank the engine. If the engine starts and runs briefly, it indicates the problem is with the fuel delivery system, not the ignition.
- Check fuses and relays: A simple cause for a no-start could be a blown fuse or a faulty relay. Locate the fuel pump fuse and relay in the vehicle's fuse box and check them for any damage. You can even try swapping the fuel pump relay with an identical one from a non-essential circuit to see if that resolves the issue.

Important safety precautions
- When working with the fuel system, wear safety glasses and have a fire extinguisher nearby.
- Ensure the engine is cool before starting any fuel system diagnostic tests.
- If you are not comfortable performing these tests, it is best to have a qualified mechanic diagnose the problem.
