Is Your 1996 GM Vehicle Running Rough, Stalling, or Refusing to Start?
If you’re dealing with a frustrating Check Engine Light, unpredictable stalling, or a car that just won’t cooperate, a failing Powertrain Control Module (PCM) is often the culprit. In my 20+ years as a technician, I’ve seen these exact issues on countless mid-90s GM vehicles. The PCM is the brain of your engine, and when it starts to fail, it can cause a cascade of problems that are difficult to diagnose. You’re not just buying a part; you’re buying a solution to get your trusted vehicle back on the road reliably.
A Technician’s Real-World Experience
“A customer’s 1996 Cavalier came in last week with these exact symptomsโit would run fine for 15 minutes, then suddenly die at a stoplight and refuse to restart for half an hour. No consistent codes, just pure frustration. We checked fuel pressure, spark, and sensors, all of which tested fine when the car was cool. The issue was heat-soak affecting the original PCM’s internal circuits. After swapping in a correctly programmed module like this one, the problem vanished instantly. These intermittent, heat-related failures are a classic sign of a dying PCM from this era.”

Common Symptoms of a Failing GM PCM:

Simple Installation: Get Back on the Road Fast
You can perform this replacement yourself with basic hand tools. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to ensure the system is fully discharged.
- Locate the PCM: On most of these GM models, the PCM is located in the engine bay, typically near the firewall or air filter housing.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the pins on the harness for any corrosion or damage. Clean them with a dedicated electronics cleaner if necessary.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed PCM into place and securely reconnect the wiring harnesses. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal. The vehicle is now ready to start.
