Where is the ecm located on 1998 Pontiac transport with 3.4 v6?

The ECM (Engine Control Module) on a 1998 Pontiac Transport with a 3.4L V6 is typically located under the hood, near the driver's side firewall. However, it's not always in the exact same spot across all vehicles. It's often mounted to the inner fender well or on a bracket attached to the firewall itself.

To be certain, you should:

* Consult your owner's manual: This is the best place to start. The manual will have a diagram showing the location of all major components, including the ECM.

* Check online resources: Websites like Haynes or Chilton provide repair manuals with diagrams for your specific year and model.

* Look for a large, rectangular black box: The ECM is usually a fairly large, black plastic box with numerous connectors. It might have labels or markings indicating its purpose.

Remember to disconnect the negative battery terminal before working near any electrical components in your vehicle.
