Is Your 2009 Savana 1500 Running Rough or Not Starting at All?
As a mechanic with two decades of experience, I’ve seen my share of work vans on the fritz. When a 2009 Savana 1500 comes into the bay with a no-start condition, random stalling, or a dashboard lit up like a Christmas tree with no clear cause, my diagnostic process often leads straight to the heart of the vehicle’s electronics: the Engine Control Module (ECM). A failing ECM can cause a cascade of frustrating, hard-to-diagnose problems, from poor fuel economy and erratic shifting to complete communication loss with your scan tool.
Expert Pro Tip from a 20-Year Veteran Mechanic
Before you condemn your ECM, do a quick but critical check. On these Savana and Express vans, the main ground wire for the ECM, located on the engine block or frame, is highly susceptible to corrosion. I’ve had dozens of vans towed in with classic ‘bad ECM’ symptoms that were fixed in 5 minutes with a wire brush and a wrench. A poor ground can mimic complete module failure. Always check your grounds and the main power connections at the underhood fuse block before replacing the part. It could save you time and money.

Plug-and-Play Installation: Get Your Van Back on the Road
Installing your new ECM is a straightforward process that a confident DIYer or any professional technician can complete. While specific steps may vary slightly by model, here is a general guide for a Savana van:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post.
- Locate the ECM: On the Savana/Express vans, the ECM is typically found in the LH rear of the engine compartment.
- Disconnect Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the module. Never force them. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed ECM and securely reconnect the wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect Battery: Re-attach the negative battery terminal. Your vehicle is now ready to start.
