Is Your GMC Safari Experiencing Mysterious Engine Problems?
If you’re dealing with a 1999, 2000, or 2001 GMC Safari that’s suddenly developed a mind of its ownโstalling for no reason, running rough, or refusing to start altogetherโyou’re likely staring down a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, when the PCM starts to go, it can create some of the most frustrating and difficult-to-diagnose issues a vehicle owner can face.
Over my two decades in the shop, I’ve seen countless GM vans and trucks from this era with these exact symptoms. The PCM, typically located by the battery on the driver’s side in your Safari, lives in a harsh environment of heat and vibration. Over time, internal connections and electronic components can degrade, leading to intermittent failures that don’t always set a clear diagnostic trouble code (DTC).
A Technician’s Real-World Experience
“A customer’s 2000 GMC Safari came in last month with a complaint that was driving him crazy. It would run perfectly for days, then suddenly die at a stoplight and refuse to restart for 20 minutes. We checked fuel pressure, spark, and sensorsโeverything looked fine. There were no codes stored. On a hunch, I tapped the PCM with a screwdriver handle while the engine was idling, and it immediately stalled. The vibrations were causing a micro-fracture on the circuit board to open up, cutting power to the fuel injectors. A replacement PCM, like this one, solved the problem instantly.”
