2010 Camaro SS Fuel Pump Control Module Location: Where It Is and How to Replace It Without the Headache

The bottom line up front: On a 2010 Camaro SS, the fuel pump control module (FPCM) is located inside the trunk, on the right-hand side near the rear quarter panel. You do not need to drop the fuel tank or remove the rear seat to access it, and the replacement process takes most DIY owners about 30 to 60 minutes from start to finish.

If you are dealing with a no-start condition, sudden engine stall, or a check engine light with codes like P069E or P0087, the FPCM is one of the first components you should inspect. The good news is that the FPCM is a standalone, serviceable module on the 2010 Camaro, which means you can test it, replace it, and get back on the road without touching the fuel tank itself.

This guide walks you through the exact location, the symptoms of a failing module, how to test it, and what replacement parts you will need, including a recommendation for a quality aftermarket fuel pump if the issue runs deeper.

1. Where Exactly Is the Fuel Pump Control Module on a 2010 Camaro SS?

The fuel pump control module on the 2010 Camaro is mounted in the right rear quarter panel area of the trunk. More specifically:

  1. Open the trunk and look at the right-hand side (passenger side) interior trim panel.
  2. The FPCM is a small black plastic module with a wiring harness connector plugged into it.
  3. It is typically secured with a few bolts or push pins behind that trim panel.
  4. On some 2010 models, the module may be positioned near the battery area, so double-check by looking for a module with a thick gauge wiring harness that runs toward the fuel tank.

Important distinction: Some online sources describe the FPCM as being "inside the fuel tank" or "part of the fuel pump assembly." That is not accurate for the 2010 Camaro. The fuel pump module (which includes the actual electric pump) is inside the tank, but the FPCM that controls it is a separate module located in the trunk. The pump itself mounts to the top of the fuel tank, and to access it you go through the rear seat area, not the trunk.

2. What Does the Fuel Pump Control Module Do?

Understanding the FPCM's job makes it much easier to diagnose problems. On the 2010 Camaro (and other 2010-2015 fifth-generation models), the fuel system is an electronic returnless on-demand design. Here is how it works:

  1. The engine control module (ECM) sends a "desired fuel pressure" message to the FPCM over the GMLAN serial data bus.
  2. The FPCM then controls the in-tank fuel pump by sending a 25 kHz pulse-width-modulated (PWM) signal to the pump.
  3. The pump speed changes based on the duty cycle of that signal, which raises or lowers fuel pressure as needed.
  4. A fuel pressure sensor on the feed line provides feedback to the FPCM, creating a closed-loop control system that keeps pressure where the ECM wants it.

The FPCM also supplies voltage to the pump only when the ignition is on, and it keeps that voltage active for about two seconds unless the engine is cranking or running.

Why this matters: The FPCM is not just a relay. It is a smart module that actively adjusts pump speed. If it fails, the pump will not run at all, or it may run at full speed without regulation, which explains the variety of symptoms owners experience.

3. Symptoms of a Failing Fuel Pump Control Module

A failing FPCM can mimic many other fuel system problems, which is why proper diagnosis matters. The most common signs include:

  1. Engine cranks but will not start. The most obvious symptom is that the starter turns the engine over, but it never fires up. Since the FPCM controls power to the pump, a dead module means no fuel delivery.

  2. Engine stalls at idle or when coming to a stop. Some owners report the car runs fine at speed but dies when the RPMs drop. This often points to the FPCM losing its ability to regulate fuel pressure at low demand.

  3. Sudden loss of power while driving. If the module fails intermittently, the pump may stop receiving the signal and the engine will lose power without warning. This can trigger a "Reduced Engine Power" message on the dash.

  4. Check engine light with fuel system codes. The most common code is P069E (Fuel Pump Control Module Requested MIL Illumination), which indicates the FPCM itself has detected a fault and asked the ECM to turn on the check engine light. Other related codes include P0087 (Fuel Rail Pressure Too Low) and P228B (Fuel Pressure Regulator Performance).

  5. No fuel pump priming sound. When you turn the key to the ON position, you should hear a brief whirring sound from the rear of the car as the pump pressurizes the system. If you hear nothing, the FPCM may not be sending power to the pump.

4. How to Diagnose the Fuel Pump Control Module

Before you buy a replacement module, take these steps to confirm the FPCM is actually the problem. You will need a digital multimeter and, ideally, a scan tool with bidirectional controls.

Step 1: Check for power at the module. With the ignition ON, verify that the FPCM is receiving battery voltage on its main power feed. If there is no power, check the fuel pump fuse and relay in the underhood fuse block. The relay itself is not a common failure point, so do not replace it without testing.

Step 2: Test the pump control circuit. Disconnect the harness connector at the fuel pump (located at the top of the fuel tank under the rear seat). Connect a test lamp between the control circuit terminal and ground. With the ignition ON, command the fuel pump ON and OFF with a scan tool. The lamp should turn on and off as commanded.

Step 3: Check the ground circuit. If the lamp does not illuminate, test the low reference circuit for an open or high resistance. If the circuits test normal but the pump still does not run, the FPCM is likely faulty.

Step 4: Verify with a scan tool. If you have access to a bidirectional scan tool, check the "desired vs. actual" fuel rail pressure. If the actual pressure is more than 218 psi (1.5 MPa) below the desired pressure for over 5 seconds, the system will trigger P0087. On the Camaro with the 6.2L engine, this is a strong indicator of a fuel delivery issue, though the root cause could be the pump or the module.

5. How to Replace the Fuel Pump Control Module

Replacing the FPCM on a 2010 Camaro SS is a straightforward job that requires no special tools. Here is the step-by-step process:

  1. Disconnect the negative battery cable. The battery is in the trunk on the driver's side. Loosen the nut on the negative terminal (black cable) and pull the cable away.

  2. Remove the right rear trunk trim panel. Use a trim removal tool to gently pry off the plastic panel covering the right quarter panel area. It is held in by push pins, so work slowly to avoid breaking them.

  3. Locate the FPCM. Once the trim is out of the way, you will see the module mounted to the body. It has one large electrical connector and is held in by two or three bolts.

  4. Unplug the connector. Press the release tab on the connector and pull it straight off the module.

  5. Remove the module. Remove the bolts and lower the module free of the vehicle.

  6. Install the new module. Position the new FPCM in place, secure it with the bolts, and plug in the connector. Make sure the connector clicks fully into place.

  7. Reinstall the trim panel and reconnect the battery. Press the trim panel back into place until the pins seat, then reconnect the negative battery cable.

  8. Prime the system. Turn the ignition to the ON position (do not start the engine) for about two seconds, then turn it OFF. Repeat this two or three times to build fuel pressure. Then start the engine and check for leaks.

Programming note: The replacement FPCM does not require dealer programming. It is a plug-and-play swap even if you purchase a used or refurbished unit. Some aftermarket suppliers may ask for your VIN to pre-program the module, but this is not necessary for the FPCM itself to function.

6. What About the Fuel Pump Itself?

The FPCM is only half the equation. If the module tests fine but the pump is weak or dead, you will need to replace the fuel pump assembly inside the tank.

Where is the pump? The primary fuel pump module is located inside the fuel tank on the right side (passenger side). To access it, you must go through the rear seat area. The factory service procedure requires dropping the fuel tank, which takes 4 to 6 hours and can cost $800 to $1,200 in shop labor. However, you can install an aftermarket fuel pump access panel to avoid that headache in the future.

Common symptoms of a failing fuel pump include:

  1. A whining noise from the rear of the car — a healthy pump is quiet, and a loud whine or screech indicates bearing wear.
  2. Loss of power under load — the engine sputters or hesitates during hard acceleration because the pump cannot maintain fuel pressure.
  3. Hot-start stalling — the car starts fine cold but stalls after a drive in warm weather, which points to pump motor overheating.

If you need to replace the pump, the access process is the same regardless of whether the pump itself is the culprit or the FPCM. Start by disconnecting the battery, relieving fuel pressure via the Schrader valve on the fuel rail, and removing the rear seat cushion to reach the access panel on top of the tank.

7. OEM Part Numbers and Interchangeability

If you decide to replace the FPCM with an OEM unit, here are the part numbers to look for:

  • 20867261 — the current production part number for the 2010 Camaro FPCM
  • 20867260 — the superseded earlier version
  • 20831727 and 20831728 — earlier module part numbers that were revised

These part numbers are interchangeable, but it is always best to install the latest version to benefit from design improvements. For the fuel pump itself, GM has updated the high-pressure fuel pump multiple times, with the latest part number being 12641847, which supersedes several earlier versions. That high-pressure pump sits on the engine (left rear), not in the tank, and is a separate component from the in-tank low-pressure pump.

9. Related Codes to Watch For

When the FPCM or fuel system is failing, the check engine light may log one or more of these codes:

  1. P069E — Fuel Pump Control Module Requested MIL Illumination
  2. P0087 — Fuel Rail Pressure Too Low
  3. P0089 — Fuel Pressure Regulator Performance
  4. P228B — Fuel Pressure Regulator Exceeded Control Limits
  5. P0231 — Fuel Pump Secondary Circuit Low

If you see any of these codes, start with the FPCM and work from there. Use a scan tool to monitor desired versus actual fuel pressure, and do not skip the simple checks like fuses and grounds.

10. Common Mistakes to Avoid

Many owners end up replacing parts that were never broken in the first place. Here are the mistakes to avoid:

  1. Throwing a fuel pump at the car without checking the FPCM. The pump can be fine while the module is dead. Always test the circuits before spending money on a fuel pump assembly.

  2. Replacing the fuel pump relay first. Relays rarely fail. A relay either works or it does not, and a failing relay will not cause low fuel pressure; it will just stop the pump entirely. Test it before replacing it.

  3. Ignoring the battery connection. The Camaro battery is in the trunk, and a corroded or loose ground there can starve the entire fuel system of power. Check battery terminal connections and the main engine grounds at G107, G108, and G109 before condemning any module.

  4. Dropping the fuel tank unnecessarily. If you only need to access the pump, you do not have to drop the tank if you install an access panel. The factory service manual method is not the only way.

  5. Assuming the FPCM needs programming. It does not. If a seller says the module must be VIN-programmed before it will work, they are either misinformed or trying to sell you a service you do not need.

11. A Quick Recap

If you take nothing else away from this guide, remember these key points:

  1. The fuel pump control module on a 2010 Camaro SS is in the trunk, right rear quarter panel area, behind the interior trim.
  2. It controls the in-tank fuel pump by varying pump speed based on desired fuel pressure from the ECM.
  3. Common failure symptoms are no-start, stalling, loss of power, and codes like P069E and P0087.
  4. Testing the module with a scan tool and a test lamp is straightforward and will tell you if the module or the pump is at fault.
  5. Replacement is a 30-minute job with no programming required.
  6. If the pump itself needs replacing, look for a quality aftermarket option like KEMSO, which offers OEM-replacement performance and a lifetime warranty. Browse the full lineup at https://www.kemsoracing.com/.
