Is Your 1997 GM Vehicle Running Rough, Stalling, or Refusing to Start?
If you’re dealing with frustrating engine problems in your 1997 Buick Century, Chevy Venture, Pontiac Grand Prix, or another compatible GM model, a failing Powertrain Control Module (PCM) is often the culprit. As a mechanic with over two decades of experience, I’ve seen how a faulty engine computer can cause a cascade of issues, from poor fuel economy and erratic shifting to a persistent Check Engine Light that won’t go away. Don’t let a bad module keep your reliable vehicle off the road. This is the direct, effective solution you need.
The Simple Solution: A VIN-Programmed 1997 Century PCM
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair. Before we ship your module, our technicians will program it with your vehicle’s specific Vehicle Identification Number (VIN) and load the latest, most stable software updates from General Motors. This ensures that the PCM communicates perfectly with your engine, transmission, and all other onboard systems, restoring the original performance and reliability your car had when it left the factory.
Expert Pro Tip: Check This Before You Replace
In my shop, I’ve seen dozens of cases where a PCM was blamed for issues caused by something much simpler. Before you install your new module, take 10 minutes to inspect the PCM’s wiring harness connectors. On these 90s GM vehicles, moisture and time can cause a green, powdery corrosion on the pins. Unplug the connectors and use a small brush and electrical contact cleaner to thoroughly clean both the harness side and the module pins. A poor connection here can mimic nearly every symptom of a failed PCM. This simple step ensures your new part has a perfect connection from the start.
Symptoms of a Failing 1997 GM Powertrain Control Module:
- โ Check Engine Light is on with various communication or sensor codes
- โ Engine stalls, stumbles, or runs rough
- โ Transmission shifts harshly, late, or not at all
- โ Complete no-start condition where the engine cranks but won’t fire
- โ Poor fuel mileage and overall lack of power
- โ Intermittent issues that get worse as the engine warms up
Plug-and-Play Installation: No Dealer Visit Required
Because we program the module to your VIN, you can perform the installation yourself and avoid a costly trip to the dealership. The process is straightforward for a DIYer with basic tools.
- Safety First: Disconnect the negative terminal from your car’s battery to prevent any electrical shorts.
- Locate the PCM: On most of these vehicles, the PCM is located in the engine bay, often inside the air filter box housing for protection.
- Disconnect the Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect and clean them as advised in the pro tip above.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed PCM, reconnect the wiring harnesses securely, and reassemble any components you removed (like the airbox).
- Reconnect the Battery: Attach the negative battery terminal. Your vehicle is now ready to start.
