Is Your GM Truck or Van Plagued by Frustrating Engine Problems?
If you’re dealing with a no-start condition, erratic shifting, a persistent check engine light, or poor fuel economy in your GMC Safari, Savana, or other compatible GM vehicle, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s reliability and performance. This module is the central command for your engine and transmission, and when it falters, the entire vehicle suffers. You need a solution that’s not just a replacement part, but a complete, reliable fix that gets you back on the road with confidence.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other sensor or component failures. If you’ve experienced any of the following, this pre-programmed module is your definitive solution:
- Unexplained Check Engine Light with codes like P0601, P0602, or P0606
- Vehicle refuses to start or stalls intermittently
- Harsh or unpredictable automatic transmission shifting
- Noticeable drop in fuel efficiency
- Failure to pass state emissions testing
- Communication errors with diagnostic scan tools

An Old Pro’s Diagnostic Tip: I once had a 2000 Chevy Express van in the shop that had its owner chasing his tail for weeks. He’d replaced the throttle position sensor, the MAF sensor, and even the fuel pump, but it still had a terrible intermittent stall. A quick scan showed no communication with the computer. Before condemning the module, we checked the basics: power and ground connections to the PCM. They were solid. That’s when we knew the brain itself was the issue. Installing a properly programmed 1999 GMC Safari PCM 16263494 solved everything in under 30 minutes. Don’t waste time and money on guesswork; a quality, pre-programmed module is the foundation of a reliable repair.
Getting your work van or family hauler back in service is our top priority. By providing us with your VIN at checkout, you ensure that the 1999 GMC Safari PCM 16263494 you receive is perfectly matched to your vehicle’s specifications, saving you time, money, and the headache of a complicated installation.
Frequently Asked Questions
Do I need to do anything after installing this PCM?
In many cases, a security relearn procedure is required. This can typically be done without special tools and involves a sequence of key turns. For vehicles with a Crankshaft Position Sensor (CKP), a CASE relearn may be needed with a compatible scan tool to prevent a P1336 trouble code. Instructions are readily available online for these simple procedures.
How do I provide my VIN number?
After completing your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. The VIN is found on your driver’s side dashboard or door jamb sticker.
Is this a new or used part?
This is a professionally serviced and inspected original equipment module. Each unit is thoroughly tested for functionality and programmed with the latest vehicle-specific software to ensure it performs reliably, just like a new component from the factory.
Will this fix my specific check engine light codes?
This PCM is a direct solution for internal module failure codes (like P0601-P0606) and communication errors. It can also resolve other codes that are a result of incorrect data from a failing computer. However, if your codes are for a specific faulty sensor (e.g., an O2 sensor), that sensor will still need to be replaced.
What is the warranty on this module?
This module comes with a comprehensive warranty to give you peace of mind. Please check the warranty tab on the listing for specific details and duration. We stand behind our programming and the quality of our components.
