2010 Camaro SS Fuel Pump Relay Location: A Complete Owner’s Guide

The fuel pump relay on a 2010 Camaro SS is located in the underhood fuse block, which sits on the right side of the engine compartment, behind the driver’s side headlamp. For the 2010 model year, the relay is part of the main engine bay fuse box, not under the dash or inside the cabin . If you are experiencing starting problems or a no‑fuel‑prime condition, checking this relay first can save you hours of unnecessary diagnostic work — and it is a thirty‑second job once you know exactly what you are looking for.

Most owners are surprised to learn how simple this is. The 2010 Camaro SS uses the same basic relay layout as other GM vehicles from that era. The underhood fuse block is a black plastic box with a removable cover that has a diagram printed on it. That diagram tells you exactly which slot belongs to the fuel pump relay. If the diagram is faded or missing, you can still identify the relay by its position and by the wiring.

Why the Fuel Pump Relay Matters on a 2010 Camaro SS

Before you start swapping parts, it helps to understand what the relay actually does. The fuel pump relay in your Camaro provides power to the fuel pump. The powertrain control module, or PCM, controls that relay. When the PCM decides the fuel pump needs to run, it energizes the relay, the internal contacts close, and power flows from the battery to the pump .

If the relay fails, the fuel pump receives no power. The engine will crank, but it will not start. That is the classic symptom. A bad relay can also cause intermittent stalling if the contacts are worn and make poor connection.

A quick and easy first test is to turn the ignition key to the “on” position without cranking the engine. You should hear a brief humming sound coming from the rear of the car. That is the fuel pump priming the system. If you hear nothing, the problem is likely in the power supply path — relay, fuse, or the pump itself .

Exactly Where to Find the Relay

Step‑by‑step instructions to locate the fuel pump relay on a 2010 Camaro SS:

  1. Park the car on a flat surface and open the hood.
  2. Look to the right side of the engine compartment, behind the driver’s side headlamp. You will see a black plastic box. This is the underhood relay center / fuse block.
  3. Remove the cover from the fuse block. The cover has a diagram printed on it. The diagram maps out every relay and fuse inside.
  4. Locate the relay labeled “Fuel Pump” or “FP.” On many GM diagrams it may also be listed under an abbreviation like “EFP” (electric fuel pump).
  5. The relay itself is a small, cube‑shaped component, usually black, with four or five prongs on the bottom. It will look identical to several other relays in the same box.

On the 2010 Camaro, all of the major relays — including the fuel pump relay — live in this single underhood fuse block. There is no separate fuel pump relay under the dash or in the trunk for this model year .

How to Test Whether the Relay Is Bad

Relays are actually one of the least likely components to fail. Some experienced technicians point out that they rarely see more than one in a hundred relays come back as truly defective . That is why it is so important to test before buying new parts.

Here is a simple way to test your fuel pump relay:

  1. Remove the relay from the fuse block.
  2. Look at the relay base or the socket. You will see four terminals. Two thin wires are typically the control circuit. The thicker wires are the power circuit.
  3. Use a multimeter set to ohms to check continuity across the power circuit terminals. If you get infinite resistance, the relay contacts may be open when they should be closed.
  4. Apply battery voltage across the control terminals. When you do this, you should hear a distinct click and continuity should be present across the power terminals. If not, the relay is likely bad.

Another practical test is the “touch and click” method. Have a helper turn the ignition to the “on” position while you keep a finger on the relay. A good relay will make a soft, distinct click as it energizes. No click means it is not engaging.

The Relay vs. the Fuse vs. the Pump

Many owners immediately blame the relay when the car will not start. But there are three separate components in that power path, and only one of them is the relay.

1. The relay acts as the switch. It either works or it does not. A relay is not going to cause low fuel pressure — that is a pump problem. As one experienced forum member put it, a relay either works or it does not, while a fuel pump can still run but fail to produce enough pressure to keep the car running through all throttle positions .

2. The fuse protects the circuit. If the fuse is blown, the pump loses power. Check the fuse first, before you buy anything. The fuse box cover diagram shows which fuse protects the fuel pump circuit.

3. The fuel pump does the actual work. On the 2010 Camaro, the fuel pump and level sensor assembly are located on top of the fuel tank, inside the tank itself . Replacing that pump is a big job — you either drop the tank or cut an access panel. That is exactly why you want to rule out the relay and fuse first.

A Common Diagnostic Mistake to Avoid

Do not throw money at parts without testing. Technicians often refuse to accept returns on parts that were used for diagnostics, and for good reason. One owner on a Camaro forum went through this exact process: the car was running poorly, he assumed the relay was the issue, and checked it, only to find the real problem was low fuel pressure. The car was bouncing at 20–25 psi while running — far below the expected range. That pointed directly to the pump, not the relay.

So before you order any parts, do a fuel pressure test if the car runs but has performance issues. Check the relay only if the pump is not priming at all.

How to Bypass the Relay for Testing (Use with Caution)

In some diagnostic situations, you may want to bypass the relay to see if the pump runs. This is a temporary test procedure only.

Here is how to do it safely:

  1. Remove the fuel pump relay from the underhood fuse block.
  2. Take a short length of small‑diameter copper wire, about five inches long, and strip roughly half an inch of insulation from each end.
  3. Insert one end of the wire into the upper‑left pin slot in the receptacle where the relay plugs in.
  4. Insert the other end of the wire into the lower‑right pin slot .

If both ends are properly seated, the fuel pump will turn on. This proves whether the pump itself works. If the pump runs when bypassed but not when the relay is installed, the relay is your problem. If the pump does not run even when bypassed, the fuse, wiring, or pump itself deserves your attention.

Recommended Upgrade: KEMSO Fuel Pumps

Final Thoughts

The fuel pump relay on a 2010 Camaro SS is easy to find once you know the layout. Open the hood, remove the cover from the underhood fuse block on the right side, and look for the relay labeled “Fuel Pump.” It takes less than a minute to check. Test before you replace, and remember that a relay either works or it does not — if your car runs but has weak pressure, the pump itself is the more likely culprit. And when you do need a new pump, choose a KEMSO unit for high performance, OEM‑grade fit, and a lifetime warranty.
