Restore Your Van’s Reliability with a Plug-and-Play Solution
Is your 2010-2012 Savana 1500 Van leaving you stranded? Stalling, hesitation, or a complete no-start condition can point directly to a failing Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen countless work vans and fleet vehicles sidelined by this exact issue. The FSCM is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to frustrating and unpredictable performance problems. This isn’t just an inconvenience; it’s lost time and money.
We offer a definitive solution: a genuine GM Fuel System Control Module, part number 20791901, that arrives at your door fully programmed to your vehicle’s specific VIN. Forget about costly dealership visits and the hassle of scheduling a programming service. We handle the complex part for you. Simply provide your VIN after purchase, and our experts will flash the module with the latest GM software updates. This ensures perfect communication with your vehicle’s computer systems and often corrects underlying drivability issues that the original factory software didn’t address.
Case Study: The “Bad Fuel Pump” That Wasn’t
A local contractor brought his 2011 Savana 1500 into my shop. It would run fine for a while, then suddenly die at a stoplight and refuse to restart for 10-15 minutes. He had already replaced the fuel pump himself, but the problem persisted. His scanner showed a P069E code (Fuel Pump Control Module Requested MIL Illumination). Instead of throwing more parts at it, we checked the FSCM. These modules are mounted on the frame rail, exposed to water, salt, and road vibration, which leads to internal corrosion and failure. We swapped in a VIN-programmed FSCM, and the van ran perfectly. He had spent hundreds on a pump he didn’t need when the real culprit was this module. This is why diagnosing correctly is key, and why a reliable, pre-programmed part is the smartest fix.
Is Your Savana Showing These Symptoms?
A faulty FSCM can mimic a bad fuel pump. Before you spend time and money dropping the fuel tank, check if your vehicle is experiencing any of these common indicators of a failing module.
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, U0109, P0230, or P2635
A Straightforward Guide to Your 2010-2012 Savana FSCM Installation
This is a repair that a confident DIYer can handle with basic tools, saving you significant labor costs. For the 2010-2012 Savana 1500 Van, the module is typically located on the driver-side frame rail.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the FSCM mounted to the inside of the driver-side frame rail, roughly below the driver’s door area. It’s a small, black box with electrical connectors.
- Disconnect and Remove: Carefully press the release tabs on the electrical connectors and pull them straight out. Then, remove the bolts or nuts holding the module to the frame. The old module should now be free.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location, securing it with the original hardware. Ensure it is snug against the frame.
- Reconnect and Finalize: Plug the electrical connectors firmly into the new module until they click into place. Reconnect the negative battery terminal. The installation is complete—no programming required!

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is essential for us to program the module with the correct GM software and calibrations for your specific engine, transmission, and options. This ensures seamless, plug-and-play installation without a trip to the dealer.
Is this part difficult to install?
For most vehicles like the Savana van, the FSCM is mounted on the frame rail and is accessible with basic hand tools. It’s considered a straightforward job for a DIY mechanic. Our installation guide above provides the key steps.
What happens if I install it without programming?
An unprogrammed module will not communicate correctly with your vehicle’s other computers. This will result in a no-start condition and will set communication-related trouble codes. Our pre-programming service eliminates this problem entirely.
How do I know if the module is bad and not the fuel pump?
Common FSCM failure codes include P069E, U0109, and P0230. A good diagnostic step is to check for power and ground at the module. Often, a failing module will work intermittently, causing stalling, which is less common for a completely failed fuel pump.
Is this a new or used part?
