Is Your 1996 Grand Am Running Rough, Stalling, or Refusing to Start?
As a mechanic with over two decades of experience, I know the frustration of chasing down electrical gremlins. If your Pontiac Grand Am is suffering from issues like erratic idling, poor fuel economy, a persistent Check Engine Light, or even a complete no-start condition, the culprit is often the Powertrain Control Module (PCM). This component is the brain of your engine, and when it fails, it can cause a cascade of confusing problems. This isn’t just a part; it’s the solution to getting your reliable GM vehicle back on the road.

Forget the hassle and expense of a dealership visit. We offer a dependable, fully tested PCM, service number 16211539, that arrives at your door ready for installation. Before we ship, our technicians will program the module using your vehicle’s specific VIN. This crucial step ensures that the computer has the latest software updates from General Motors and is perfectly matched to your car’s engine, transmission, and options.

Expert Pro Tip: Check Your Connectors First!
On these mid-90s GM vehicles, the large multi-pin connectors on the PCM can be a source of trouble. Before you condemn your old module, disconnect the battery and carefully inspect the pins on both the harness and the old PCM for any signs of green or white corrosion. Cleaning them with a dedicated electronics cleaner and a small brush can sometimes resolve intermittent issues. If the problem persists, a failing module is the most likely cause.
