Is Your 1996 GM Vehicle Running Rough, Stalling, or Refusing to Start?
If you’re dealing with frustrating and unpredictable engine problems in your 1996 Buick Skylark or a similar GM model, a failing Powertrain Control Module (PCM) is often the culprit. Over two decades in the shop, I’ve seen how a bad PCM can mimic a dozen other issues, leading to wasted time and money on parts you don’t need. This isn’t just a component; it’s the brain of your engine and transmission, and when it falters, the symptoms can be maddening.
Stop Guessing and Start Driving Again
This replacement PCM, part number 16211539, is the definitive solution to get your vehicle running reliably. We take the guesswork and hassle out of the repair. Before this module ships, we will program it with the latest GM software updates, specifically calibrated to your vehicle’s unique Vehicle Identification Number (VIN). This means no expensive trips to the dealership for programmingโit arrives ready for installation.
Common Symptoms of a Failing 1996 GM PCM:
- โ Unexplained stalling or cutting out while driving
- โ Harsh or erratic automatic transmission shifting
- โ Complete no-start condition with power to all other accessories
- โ Persistent Check Engine Light with communication error codes
- โ Poor fuel economy and a noticeable loss of power
- โ Intermittent issues that get worse in hot or cold weather
From the Shop Floor: A Real-World Diagnosis
“A customer’s 1996 Pontiac Grand Prix came in last month on a tow truck. It would crank but never start, and the owner had already replaced the fuel pump and ignition module. The scan tool couldn’t even communicate with the computer. After verifying the PCM had proper power and ground at the connectors, we knew the module itself was the failure point. These older units can suffer from internal board failure after decades of heat cycles. We installed a VIN-programmed PCM just like this one, and the car fired right up and ran perfectly. It’s a classic failure mode for these vehicles.”
