Is Your 1996 GM Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
If you’re dealing with frustrating engine problems in your 1996 Pontiac Sunfire, Cavalier, or another GM model from that era, a failing Powertrain Control Module (PCM) is often the culprit. Over my 20+ years in the shop, I’ve seen these specific modules cause some of the most confusing issues—from random stalling at stoplights to a complete no-start condition that leaves you stranded. You don’t have to keep guessing or throwing parts at the problem. This is the reliable, straightforward solution you need.
This isn’t just a replacement part; it’s a fully integrated solution. We program this PCM with the latest official GM software updates using your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the computer communicates perfectly with your engine, transmission, and all related sensors, restoring the performance and reliability you expect from your vehicle.
A Real-World Diagnostic Story
“A customer’s 1996 Chevy S10 with the 2.2L engine came into my shop last month with a classic intermittent no-start. It would run fine for days, then refuse to start for an hour. We checked for spark and fuel pressure during one of the episodes, and both were absent. The scan tool couldn’t even communicate with the PCM. After confirming the power and ground feeds to the computer were solid, we knew the PCM itself was failing internally, likely due to heat cycles causing hairline cracks in the circuit board. We installed one of our VIN-programmed PCMs, and the truck fired up on the first try and has been running perfectly ever since. It’s a common failure point I’ve diagnosed hundreds of times on these mid-90s GM vehicles.”

You can install this module yourself with basic hand tools. Follow these simple steps to restore your vehicle’s brain.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most of these vehicles, the PCM is located in the engine bay, often near the firewall or battery.
- Disconnect and Remove: Carefully unplug the electrical connectors. There are typically release tabs you’ll need to press. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed PCM into place and securely reconnect all electrical harnesses. Make sure they click into place.
