Is Your GM Vehicle Running Rough, Stalling, or Refusing to Start?
If you’re dealing with a persistent check engine light, erratic transmission shifting, or frustrating no-start conditions in your late-90s GM car, the Powertrain Control Module (PCM) is a very likely culprit. Over two decades on the road, the complex electronics inside these modules can degrade, leading to a host of performance problems. In my shop, I’ve seen countless vehicles like the Olds Intrigue, Pontiac Grand Am, and Buick LeSabre come in with issues that owners have spent hundreds trying to fix, only to discover the root cause was the vehicle’s computer.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a quality-tested PCM, part number BXAD, and flash it with the latest official GM software calibrated specifically to your vehicle’s VIN. This critical step ensures all components communicate correctly, restoring the original performance and efficiency you’ve been missing. Forget expensive dealership visits and programming fees—this module arrives at your door ready for a straightforward installation.
Common Symptoms of a Failing GM PCM
- ✔ Unexplained Check Engine Light illumination
- ✔ Harsh or delayed automatic transmission shifts
- ✔ Engine stalling, sputtering, or intermittent no-start issues
- ✔ Noticeable decrease in fuel economy
- ✔ Communication error codes with a scan tool
- ✔ Failure to pass emissions testing
Expert Pro Tip from a 20-Year Technician
Before installing your new PCM, take a moment to carefully inspect the wiring harness connectors. Over the years, moisture and vibration can cause corrosion on the pins or loosen the terminals. Use a small brush and quality electronic contact cleaner to gently clean both the male and female ends of the connectors. A poor connection is one of the most common reasons I’ve seen for a replacement module to fail prematurely or not work at all. A clean, secure connection is essential for proper function.

Simple Installation Process
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning work.
- Locate the PCM: On most of these GM models, the PCM is found either in the engine bay (often inside the air filter box) or under the dashboard on the passenger side.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new PCM into place and securely reconnect the wiring harnesses. You should hear a ‘click’ as they lock.
- Final Step: Reconnect the negative battery terminal. The vehicle may need to complete a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes before starting.
