Video: Video - Checking error Codes

This is an excellent article that describes how to check for errors codes when your Check Engine light is on. Also tells you how to diagnose the Fiero ECM to determine if it has failed, as well as which wires in the harness to check to ensure your ECM is getting power and signal.
