Is Your 1996 GM Vehicle Running Rough, Stalling, or Refusing to Start?
If you’re dealing with frustrating and intermittent issues on your 1996 Chevrolet Lumina or another GM model from that era, a failing Powertrain Control Module (PCM) is a very common culprit. After 20+ years on the road, the original electronics can break down, leading to a cascade of problems that are often difficult to diagnose. This isn’t just an inconvenience; it’s a reliability issue that can leave you stranded. Stop chasing phantom sensor codes and get to the root of the problem with our fully programmed PCM, part number 16211539.
The Direct Solution for Common PCM Failures
In my shop, I’ve seen these exact modules cause some of the most confusing symptoms. A customer might experience a car that runs perfectly when cold but stalls at a stoplight once it’s warmed up.

Expert Pro Tip: Check for This Common Misdiagnosis
A classic symptom of a failing 1996 GM PCM is heat-related failure. The vehicle might start and drive fine for 15-20 minutes, then suddenly stall and refuse to restart until it has cooled down completely. Many technicians mistakenly blame the crankshaft position sensor or ignition control module. Before replacing those parts, try this: when the no-start condition occurs, carefully feel the PCM. If it’s extremely hot to the touch, it’s a strong indicator that internal circuits are failing under heat, and the PCM itself is the problem.
Easy Installation for the DIY Mechanic
You don’t need to be a master technician to replace this module. With basic hand tools, you can have your car back on the road in under an hour. Follow these simple steps for a successful installation.
- Safety First: Disconnect the negative terminal from your car’s battery to prevent any electrical shorts.
- Locate the PCM: On most 1996 GM cars like the Lumina, the PCM is located in the engine bay, often inside the air filter box housing for protection and cooling.
- Disconnect the Connectors: Carefully unclip and remove the electrical wiring harnesses from the old PCM. Inspect the pins on the connectors for any corrosion or damage and clean them if necessary.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed PCM into the bracket and securely reconnect the wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect the Battery: Re-attach the negative battery terminal. The vehicle is now ready to start. It may take a few drive cycles for all systems to fully sync.
