Is Your 1998 Savana Van Giving You Headaches?
If you’re dealing with a no-start condition, intermittent stalling, erratic shifting, or a persistent Check Engine Light on your 1998 GMC Savana 1500, the Powertrain Control Module (PCM) is a very likely culprit. Over two decades of experience in the shop has shown me that these specific PCMs, often located in the harsh environment of the engine bay, are prone to failure from years of heat cycles and vibration. You might be pulling codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (PCM Processor Fault), which are dead giveaways for an internal module failure.
A Technician’s Real-World Story
“A customer’s 1998 Chevy Express 2500, which uses this same PCM, came in on a tow truck last month. It would crank but never start. He’d already replaced the fuel pump and ignition coil. After checking for spark and fuel pressure, which were present, we hooked up the scan tool. The tool couldn’t communicate with the PCM at all. We checked the power and ground feeds to the module, and they were perfect. That’s a classic signโwhen the module has power but won’t talk, the brain is dead. We installed one of our pre-programmed modules, and the van fired up on the first try. It saved the customer hundreds compared to a dealer diagnosis and repair.”

Easy Installation Process
While professional installation is always recommended, this is a job many DIYers can handle. Hereโs a typical process for a Savana or Express van:
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On your 1998 Savana, it’s typically found on the driver’s side of the engine compartment, near the battery or firewall.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. There are usually levers or tabs that need to be released. Then, unbolt the module from its bracket.
- Install the New Module: Bolt the new PCM into place and securely reconnect the wiring harnesses. You should feel a solid click as they lock in.
- Reconnect Power: Reconnect the negative battery terminal.
- Security Relearn (If Necessary): In some cases, a simple security relearn procedure may be needed. This usually involves turning the key to the ‘ON’ position for 10-15 minutes. Your vehicle’s service manual will have the specific steps if required.
By ordering this pre-programmed module, you’re not just buying a partโyou’re getting a vehicle back to its reliable, smooth-running self with the confidence of an expert-backed solution.
