Restore Power and Reliability to Your 2010-2012 GMC Savana 1500
Is your Savana van suddenly stalling, struggling to start, or showing a check engine light? These are classic signs of a failing Fuel System Control Module (FSCM). This crucial component is the brain behind your fuel pump, regulating fuel pressure and delivery. When it fails, it can leave you stranded. This isn’t just an inconvenience; for a work van, it’s lost time and money. We offer a direct-fit, reliable solution to get your vehicle running smoothly again.
This is a genuine GM Fuel System Control Module, part number 20827745, that arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load the latest GM software updates before shipping, eliminating the need for an expensive trip to the dealership for programming. This makes the repair faster, simpler, and more affordable for both professional mechanics and DIYers. Simply provide your VIN at checkout, and we handle the rest.
From the Diagnostic Bay: The Ghost of a Bad Ground
A customer brought in a 2011 Sierra with a classic no-start complaint. The engine would crank but never fire. He had already replaced the fuel pump, thinking that was the obvious culprit. The scanner showed code P069E – Fuel Pump Control Module Requested MIL Illumination. In my experience, while this code points to the FSCM, the root cause isn’t always the module itself. These modules are often mounted on the frame rail, exposed to road salt and moisture. I’ve seen dozens where the ground connection corrodes, causing erratic voltage and frying the module over time. After confirming the new FSCM fixed the issue, I made sure to clean the frame mounting point to bare metal and apply dielectric grease to the new ground connection. It’s a five-minute step that prevents a repeat failure down the road.
Is Your Savana Showing These Symptoms?
A failing FSCM can cause a range of frustrating issues. If you’re experiencing any of the following, this module is the likely solution. Look out for these common signs and diagnostic trouble codes (DTCs):
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially under load
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor performance
- ✔ Noticeable decrease in fuel economy
- ✔ Check Engine Light illuminated with codes such as P069E, U0109, P0230, or P0606
A Straightforward Guide to Installation
Replacing the FSCM on your Savana is a manageable job for a confident DIYer. Since we program the module for you, no special scan tools are needed for the installation. Always follow proper safety procedures.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On the 2010-2012 Savana 1500, the FSCM is typically mounted on the driver-side frame rail, near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, remove the bolts or nuts holding the old module to the frame. These can be rusty, so a little penetrating oil might help.
- Prepare the Mounting Surface: As mentioned in my diagnostic story, it’s critical to clean the mounting point on the frame to ensure a solid ground connection. Use a wire brush to remove any rust or corrosion.
- Install the New Module: Bolt the new, pre-programmed FSCM securely to the clean frame surface. Reconnect the electrical connectors, ensuring they click into place.
- Final Steps: Reconnect the negative battery terminal. The vehicle may require a few key cycles or a short drive for all systems to reset and recognize the new module.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s 17-digit VIN during or after checkout, and it will arrive ready to install.
What happens if I don’t provide my VIN?
Providing your VIN is required for this part. We cannot ship the module until we program it, as it will not function correctly in your vehicle without the proper software matched to your VIN.
Is this part difficult to install?
For most of the trucks and vans listed, the FSCM is mounted on the frame rail, making it accessible with basic hand tools. Since it’s pre-programmed, it’s a plug-and-play electrical component, which is a straightforward job for most DIYers.
Will this fix a P069E check engine light code?
Yes, in the vast majority of cases, a faulty FSCM is the direct cause of a P069E code. Replacing the module with this pre-programmed unit is the standard, effective repair for this issue.
What is the difference between an FSCM and a fuel pump?
The fuel pump is a mechanical device in the fuel tank that moves gasoline. The Fuel System Control Module (FSCM) is an electronic computer that tells the fuel pump how fast to run to maintain correct fuel pressure. They work together, but are separate parts.
