Is Your GM Truck or Van Running Rough?
If you’re dealing with frustrating issues like a no-start condition, erratic shifting, random stalling, or a persistent check engine light, a failing Powertrain Control Module (PCM) is often the culprit. For workhorses like the 1998 GMC Savana 2500 and other compatible GM vehicles, the PCM is the brain of the operation. When it fails, it can bring your work or your daily life to a grinding halt. This isn’t just an inconvenience; it’s downtime that costs you time and money. You need a reliable, straightforward solution that gets you back on the road without the hassle and expense of a dealership visit.
Common Symptoms & Your Solution
A faulty engine computer can manifest in numerous ways. You might be experiencing one or more of the following:
- No-Start or Hard Starting: The engine cranks but refuses to fire up, or takes an excessive amount of time to start.
- Poor Performance: Noticeable loss of power, terrible fuel economy, and sluggish acceleration.
- Harsh or Incorrect Shifting: The transmission may slam into gear, shift at the wrong times, or fail to shift at all.
- Check Engine Light with Communication Codes: Diagnostic trouble codes (DTCs) like U0100 (Lost Communication with ECM/PCM) or various P-codes related to sensor circuits can point to an internal module failure.
This Programmed 09366810 PCM is the definitive fix for these problems. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures that it has the correct software and calibrations for your engine, transmission, and options, making the installation process as simple as possible.

Expert Insight: The ‘Black Box’ Myth
As a mechanic for over 20 years, I’ve seen countless DIY’ers get stuck after replacing a PCM. They install a used unit from a junkyard, and the truck still won’t start. Why? Because on these late-90s GM vehicles, the PCM is coded to the original vehicle’s VIN and security system (Passlock/VATS). It’s not a simple swap. Our programming service is what makes this a true plug-and-play solution. We handle the complex ‘digital handshake’ between the module and your vehicle beforehand, saving you from a tow to the shop and hours of diagnostic headaches. This is the professional-grade fix that gets the job done right the first time.
