Is Your 1998 Venture Running Rough, Stalling, or Shifting Erratically?
As a mechanic with over two decades of experience, I’ve seen countless 1998 Chevrolet Ventures come into the shop with baffling issues. The owner is frustrated, they’ve often replaced multiple sensors, and the van still isn’t reliable. More often than not, the culprit is a failing Powertrain Control Module (PCM). If you’re dealing with poor performance, hard starting, or a persistent check engine light, you’ve found the reliable, long-term solution.
From the Shop Floor: “A customer’s ’98 Venture was towed in last month. It would crank but not start. They had already replaced the fuel pump and the crank sensor based on some forum advice. After a quick diagnostic check, I found no signal from the PCM to the fuel pump relay. The PCM’s internal driver had failed—a classic issue I’ve diagnosed on at least 100 of these GM 3.4L engines. We installed one of our pre-programmed modules, and it fired right up. It’s a fix that saves customers time, money, and a lot of guesswork.”

Common Symptoms of a Failing 1998 Venture PCM:

Simple Installation to Get You Back on the Road
You don’t need to be a master technician to install this part. With basic hand tools, you can have your Venture running smoothly again in under an hour.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On the 1998 Venture, the PCM is typically located inside the air filter housing assembly in the engine bay.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed PCM into place and securely reconnect the wiring harnesses.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Security Relearn: This is a vital step. Turn the key to the ‘ON’ position for 10-15 minutes, then turn it off for 10 seconds. Repeat this cycle three times. This allows the vehicle’s anti-theft system (VATS/Passlock) to sync with the new PCM. The vehicle will not start until this is completed.
Expert Pro Tip: Before you install the new module, take a moment to clean the wiring harness connectors with a dedicated electronics cleaner. Over the years, dirt and moisture can build up, causing poor contact and intermittent issues that can mimic PCM failure. A clean connection ensures a reliable repair.
