Is Your 1996 GM Vehicle Running Poorly?
If you’re experiencing frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a no-start condition in your 1996 Buick Regal, Grand Prix, Lumina, or another compatible GM model, the root cause is often a failing Powertrain Control Module (PCM), also known as the Electronic Control Module (ECM). This component is the brain of your vehicle, managing everything from fuel injection and ignition timing to transmission shifting. When it fails, it can cause a wide range of perplexing and performance-robbing problems.

Before we ship the unit, our technicians will program it with the latest GM-certified software updates specifically for your vehicle’s Vehicle Identification Number (VIN). This ensures that the module is a true plug-and-play replacement, ready for installation right out of the box. It will function precisely as the original unit did, restoring your vehicle’s performance, reliability, and efficiency.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough idling, misfires, or hesitation during acceleration.

Why Choose a VIN-Programmed Module?
In 1996, vehicles began using more complex OBD-II systems with security features like GM’s Pass-Key or VATS system. Simply swapping a used computer from another vehicle will not work, as it won’t be matched to your car’s specific options and anti-theft system. Our service handles this critical step for you. By providing your VIN, you receive a module that is:
- Correctly Calibrated: Programmed for your specific engine, transmission, and emissions equipment.
- Updated: Flashed with the newest software from General Motors to address known factory bugs and improve performance.
- Ready for Installation: Eliminates the need for expensive programming tools or a trip to the dealership.
