Common Issues & How This Fixes Them
In my years fixing GM vehicles, I’ve encountered owners of 1998 Savana 2500 vans facing no-start conditions, where the engine cranks but won’t fire—often due to a corrupted PCM failing to communicate with the ignition system. This stems from electrical surges or age-related degradation, leading to DTCs like P0601 for internal control module memory errors. Replacing with this programmed PCM resolves it by restoring proper signal processing. Another frequent problem is intermittent stalling during acceleration, caused by faulty fuel trim adjustments; the updated module recalibrates these for stable operation. Think of a delivery driver losing power mid-route—this fix prevents that by optimizing air-fuel ratios. Additionally, check engine lights from sensor misreads, such as oxygen or throttle position, get cleared as the new PCM integrates fresh data protocols. For rough idling in cold weather, common in these vans, the module’s enhanced algorithms smooth out the rpm fluctuations. Always scan for codes first; if it’s PCM-related, this direct replacement avoids costly dealer visits. Drawing from shop scenarios, one client towed their van after repeated failures—post-install, it ran flawlessly, saving downtime.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the PCM with the latest GM updates tailored to your 1998 Savana 2500.
- Disconnect the battery to ensure safety and reset any residual codes before starting the swap.
- Locate the PCM in the left front engine compartment, remove the mounting bolts, and unplug the connectors carefully to avoid damaging pins.
- Install the new PCM by securing it in place and reconnecting all harnesses firmly.
- Reconnect the battery and perform a CASE relearn if needed—drive the vehicle at varying speeds for 10-15 minutes to allow the crankshaft position sensor to synchronize.
- If the vehicle doesn’t start post-install due to security protocols, conduct a theft deterrent relearn: Insert key, turn to ON for 10 minutes, off for 30 seconds, repeat three times—our programming minimizes this, but it’s a simple fix if required.
