Restore Your Vehicle’s Brain and Get Back on the Road
If you’re dealing with frustrating issues like stalling, a no-start condition, or a persistent check engine light on your 1996 GM vehicle, the problem often points to a failing Powertrain Control Module (PCM). As a technician with over two decades of experience, I’ve seen how a faulty engine computer can cause a cascade of problems that are difficult to diagnose. This isn’t just a part; it’s the central command center for your engine’s performance, fuel economy, and emissions. This replacement 1996 Skylark PCM is the reliable, straightforward solution to bring your car or truck back to life.
We take the guesswork and hassle out of the repair. Unlike a generic module from a parts store, this PCM is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This process ensures all factory settings are correct and includes the latest operational software updates from General Motors. This means no expensive trips to the dealership for programming—it’s ready for installation right out of the box.
From the Diagnostic Bay
I remember a 1996 Chevy S10 that came into my shop on a tow truck. The owner had replaced the fuel pump and ignition coil, but it still had an intermittent crank-no-start issue. The engine would fire up perfectly one day and be completely dead the next. After confirming fuel pressure and spark were indeed dropping out together, my suspicion turned to the PCM. A simple diagnostic trick confirmed it: a light tap on the PCM housing with a screwdriver handle caused the engine to stall immediately. This is a classic sign of failing internal solder joints, a common issue in modules from this era. We installed a VIN-programmed PCM, and the truck has been running reliably ever since. This part solves those frustrating, intermittent electrical gremlins.
Common Signs Your Engine Computer is Failing
- ✔ Check Engine Light is on with codes like P0601 (Internal Control Module Memory Check Sum Error)
- ✔ Engine cranks but will not start
- ✔ Intermittent stalling or rough idling
- ✔ Noticeable decrease in fuel economy
- ✔ Automatic transmission shifts erratically or harshly
- ✔ No communication with your diagnostic scan tool
- ✔ The vehicle fails an emissions test
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- ✔ Locate the PCM: On most of these 1996 GM models, the PCM is located in the engine bay, often near the battery or inside the air filter housing. Consult a repair manual for your specific model if you’re unsure.
- ✔ Disconnect Connectors: Carefully unlatch and remove the electrical wiring harnesses connected to the old module. Inspect the connectors for any corrosion or damage.
- ✔ Remove the Old Module: Unbolt the old PCM from its mounting bracket. It’s typically held in place by a few small bolts.
- ✔ Install the New PCM: Mount your new, pre-programmed PCM onto the bracket and secure it with the original bolts.
- ✔ Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reconnect the negative battery terminal.
- ✔ Final Check: Turn the key to the ‘On’ position for 10 seconds before starting the engine. This allows the system to recognize the new module. Start the vehicle and check for proper operation.

Do I really need to provide my VIN?
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is essential. We use it to program the module with the exact software and calibrations for your vehicle’s specific options, ensuring perfect compatibility and performance right out of the box.
Is any extra programming required after I install it?
No. This PCM arrives fully programmed and ready for installation. You will not need to take the vehicle to a dealer or mechanic for additional programming, saving you time and money.
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls critical functions like fuel injection timing, spark timing, transmission shifting, and emissions systems to ensure the engine runs efficiently and smoothly.
Where is the PCM located on my 1996 vehicle?
On most 1996 GM cars and small trucks, the PCM is found under the hood. Common locations are on the firewall, near the battery, or integrated into the air cleaner assembly. A quick search for your specific model will confirm its location.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (like code P0601), then yes, this replacement part will resolve the issue. However, you should always diagnose the codes to ensure the fault isn’t with a different sensor or component.
