Is Your GM 3.6L Vehicle Running Rough?

A failing Engine Control Module (ECM) can be the source of countless frustrating and hard-to-diagnose issues. As the central computer for your engine, the ECM controls everything from fuel mixture and ignition timing to transmission shift points and emissions. When it starts to fail, you’ll notice. Your vehicle might refuse to start, stall unexpectedly, get terrible gas mileage, or have a persistent Check Engine Light that no amount of part-swapping seems to fix. Don’t let a faulty computer keep your car off the road. This genuine, road-tested ECM is your direct-fit, reliable solution.

From the Diagnostic Bay

We had a 2007 Cadillac CTS with the 3.6L V6 come into the shop with a bizarre, intermittent stalling problem. The owner had replaced the crank sensor, cam sensors, and even the fuel pump, but the car would still die randomly at stoplights. No codes were stored consistently. After hours of chasing wires, we hooked up a scope to the injector command signals from the ECM. We found that the signal for injector #3 would just drop out randomly, starving the cylinder of fuel and causing the stall. A new ECM wasn’t the first thought, but it was the right one. We installed a VIN-programmed unit just like this one, performed the security relearn, and the car ran perfectly. It’s a classic case of how a failing computer can mimic a dozen other mechanical problems.

Common Symptoms of a Failing Buick Allure ECM

  • ✔ Check Engine Light: The most common sign, often with communication-related codes (U-codes) or multiple random sensor codes.
  • ✔ No-Start or Hard Starting: The engine cranks but won’t fire up, or takes an excessively long time to start.
  • ✔ Engine Stalling: The engine may stall unexpectedly while driving or when coming to a stop.
  • ✔ Poor Performance & Fuel Economy: Noticeable loss of power, hesitation during acceleration, and a sudden drop in MPG.
  • ✔ Rough Idle or Misfiring: The engine runs erratically, and you may feel shaking or shuddering.
  • ✔ Transmission Issues: Harsh shifting or failure to shift correctly, as the ECM often works with the Transmission Control Module.

The Plug-and-Play Solution You Need

Replacing an ECM isn’t just about swapping a box. Modern vehicles have sophisticated anti-theft systems and vehicle-specific software. This unit eliminates the guesswork and the need for expensive dealership tools. We take this tested, used ECM and program it specifically to your vehicle’s Vehicle Identification Number (VIN). This process loads the correct software and calibrations for your car’s exact configuration, ensuring seamless integration. It’s as close to a plug-and-play repair as you can get.

IMPORTANT: After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot ship your part until we have this information to perform the programming service. This ensures you receive a part that is ready for your vehicle.

Frequently Asked Questions

Will I need to do anything after installing this ECM?

In most cases, you will need to perform a security relearn procedure. This syncs the new ECM with your vehicle’s anti-theft system and keys. This procedure is often simple and can be done without special tools (e.g., the “30-minute relearn”). We recommend searching for the specific procedure for your year and model. A Crankshaft Variation (CASE) relearn may also be required, which typically needs a capable scan tool.

How do I provide my VIN for programming?

You can add your 17-digit VIN in the “notes to seller” section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN before we program and ship the module.

Is this a new part?

No, this is a high-quality, used OEM part sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure full functionality before being programmed and shipped. This provides a reliable and cost-effective alternative to a new dealership part.

My original part number is 12592124. Will this part work?

Yes. This ECM, part number 19260507, is a superseding part and is a direct, compatible replacement for service numbers 12592124, 12581144, and 12588472. As long as your vehicle is on the fitment list, it will function correctly.

What happens if I install this without providing a VIN?

We do not ship modules without programming them first. An unprogrammed ECM will not allow the vehicle to start due to the anti-theft system and incorrect engine parameters. Providing your VIN is a mandatory step to ensure you receive a functional, vehicle-specific part.
