2014 Chevy Impala Fuel Pump Relay Location: Where to Find It and How to Test It

If you drive a 2014 Chevy Impala and it cranks but won't start, or stalls without warning, the fuel pump relay is one of the first things you should check. On the 2014 Chevy Impala, the fuel pump relay is located in the engine compartment fuse block, also known as the underhood fuse box. This box sits near the front of the engine bay, typically on the driver's side or passenger's side depending on your trim level. Inside the fuse block, the relay is clearly labeled on the underside of the fuse box cover. If you flip the cover over, you will see a diagram that shows exactly which slot controls the fuel pump. This guide will walk you through finding the relay, understanding how it works, testing it, and knowing when to replace it so you can get your Impala running again.

Why the Fuel Pump Relay Matters on Your 2014 Impala

The fuel pump relay acts as the gatekeeper between your battery and the fuel pump. The engine control module (ECM) sends a small ground signal to the relay coil, which then closes an internal switch and sends full battery voltage to the fuel pump. Without this relay, the fuel pump would either run constantly — draining your battery and burning out the pump — or never run at all.

On the 2014 Impala, when you turn the key to the ON position, you should hear a faint two-to-three second whir from the rear of the car. That sound is the fuel pump priming the system. If you hear nothing, the relay may not be closing, or the pump itself may be dead.

Step-by-Step: Finding the Fuel Pump Relay on a 2014 Chevy Impala

Here is how to locate the relay without guessing:

  1. Park safely and turn off the engine. Set the parking brake and remove the key from the ignition.

  2. Open the hood and locate the underhood fuse block. On the 2014 Impala, this is a black plastic box near the battery. It usually has a removable cover with a diagram printed on the inside.

  3. Remove the fuse block cover. Press the tabs on the sides and lift the cover straight up. Do not force it.

  4. Read the diagram on the cover. Look for the label that says FUEL PUMP or FP. The diagram will show you the exact position of the relay in the block.

  5. Identify the relay by its shape. A standard automotive relay is a small rectangular or cube-shaped component with four or five metal pins on the bottom. It will be about one inch tall.

  6. Pull the relay straight out. Use a relay puller tool or a pair of needle-nose pliers. Never pry it with a screwdriver, as you can damage the socket.

If your Impala's fuse box cover is missing or the diagram is faded, you can find the relay by looking for the label printed directly on the fuse block itself. Some 2014 Impala models also have a secondary fuse box inside the cabin, but the fuel pump relay is almost always in the underhood box.

How to Test the Fuel Pump Relay

Before you spend money on a new relay, test the old one. Here is a simple procedure:

  1. Swap the relay with a known good one. Find another relay in the same fuse box that has the same part number — for example, the horn relay or the air conditioning relay. Swap them and try to start the car. If the engine starts, the original fuel pump relay was bad.

  2. Listen for the click. Have a helper turn the key to ON while you hold the relay. You should feel and hear a distinct click when the relay energizes. No click means the coil is dead.

  3. Test the coil with a multimeter. Set your meter to ohms. Touch the probes to pins 85 and 86 on the relay. You should read between 50 and 120 ohms. A reading of zero or infinity means the relay is faulty.

  4. Check for power at the socket. With the key on, use a test light to confirm 12 volts at terminal 30 and terminal 86 in the fuse box socket. If power is missing, the problem is a fuse or wiring, not the relay.

  5. Test the ground signal. The ECM provides a ground to terminal 85. If you do not see a ground pulse when cranking, the ECM or its wiring may be the issue.

Common Symptoms of a Bad Fuel Pump Relay on a 2014 Impala

A failing relay can mimic a dead fuel pump, so knowing the signs saves you from replacing the wrong part. Watch for these symptoms:

  1. Engine cranks but will not start. The most common sign. The starter turns the engine over, but no fuel reaches the cylinders because the relay never sends power to the pump.

  2. Intermittent stalling. The relay may fail when hot or vibrate loose. The car runs fine, then dies without warning. After a few minutes, it restarts and runs again.

  3. No fuel pump prime sound. When you turn the key, you hear silence instead of the usual two-second whir from the tank.

  4. Fuel pump runs constantly. Less common, but if the relay sticks closed, the pump runs even with the key off. This drains the battery and can overheat the pump.

  5. Check engine light with fuel system codes. Codes like P0230 (fuel pump primary circuit malfunction) or P0087 (fuel rail pressure too low) often point to a relay or pump issue.

What If the Relay Is Not the Problem?

If you replace the relay and the car still will not start, the issue may be elsewhere. Here are the next steps:

  1. Check the fuel pump fuse. Locate the fuel pump fuse in the same underhood box. Pull it out and inspect the metal strip inside. If it is broken, replace it with a fuse of the same amperage.

  2. Test the fuel pump itself. Access the fuel pump connector at the tank. With the key on, check for 12 volts at the pump. If voltage is present but the pump does not run, the pump is dead.

  3. Inspect the wiring. Look for corroded connectors, broken wires, or poor grounds near the tank and along the frame. A bad ground can cause the same symptoms as a bad relay.

  4. Check the fuel pump control module. Some 2014 Impala models use a separate fuel pump control module. Codes like P025A or P069E point to this module rather than the relay.

  5. Scan for diagnostic trouble codes. A scan tool can reveal codes that narrow down the fault to the relay, the pump, the wiring, or the ECM.

2014 Chevy Impala Fuel Pump Replacement Cost

If your diagnosis leads to a failed fuel pump rather than just the relay, here is what you can expect to pay. The fuel pump on a 2014 Impala is located inside the fuel tank, which makes the job labor-intensive. Based on market data for similar Chevrolet models, the fair repair range for a fuel pump replacement is between $1,100 and $1,471. Parts typically cost between $500 and $662, while labor ranges from $600 to $809. Dealership prices tend to be higher, often reaching the top of that range, while independent shops charge less. Additional components like the fuel filter, fuel pump relay, or fuel tank pressure sensor may need replacement at the same time, which can add $45 to $200 to the total.

When to Call a Professional

While replacing a fuel pump relay is a job most DIY enthusiasts can handle, fuel pump replacement is a different story. The pump sits inside the fuel tank, and accessing it requires either dropping the tank or removing the rear seat to reach an access panel. This work involves handling fuel lines, electrical connections, and potentially dangerous fuel vapors. If you are not comfortable working with fuel systems, or if you do not have the proper tools, have a certified mechanic perform the repair. The cost of professional labor is far less than the risk of a fuel leak or fire.

For relay testing and replacement, however, most owners can safely do the job in their own driveway with basic hand tools. Just remember to disconnect the negative battery cable before working on any electrical component, and never smoke or use open flames near the fuel system.

Final Thoughts

The 2014 Chevy Impala fuel pump relay location is in the underhood fuse block, and finding it takes only a few minutes. Test the relay before replacing it, and if the relay checks out, move on to the fuse, the pump, and the wiring. A failed relay is one of the most common and least expensive causes of a no-start condition on this vehicle. Keep a spare relay in your glovebox — it is a small part that can save you from being stranded. And when the fuel pump itself finally gives out, trust KEMSO for a high-performance, OEM replacement with a lifetime warranty.
