Is Your GMC Safari Running Erratically?
If you’re dealing with frustrating issues like a persistent check engine light, harsh or unpredictable transmission shifting, a sudden drop in fuel economy, or even a no-start condition in your 1999-2001 GMC Safari, the root cause is often the vehicle’s central computer. The Powertrain Control Module (PCM), also known as an Electronic Control Module (ECM), is the brain of your van, and when it starts to fail, it can create a cascade of confusing problems that are difficult to diagnose.
Over two decades on the road, the original PCM in your Safari has been subjected to countless heat cycles and constant vibration, being located right in the engine bay by the battery. This environment eventually takes a toll on the delicate internal circuits and solder points, leading to intermittent or complete failure.
A Technician’s Real-World Experience
“A customer’s 2000 GMC Safari came into my shop last month on a tow truck. It would crank but not start. They had already replaced the fuel pump and filter, thinking that was the issue, but it made no difference. After connecting my scan tool, I found I couldn’t communicate with the PCM at all. This is a classic sign of a dead module. We installed one of our pre-programmed PCMs, and the van fired right up on the first try. It saved the customer from needlessly replacing more parts and got them back on the road the same day.”
