ECM, or Electronic Control Module, typically derives its power from the vehicle's battery and is connected to the electrical system of the vehicle. It operates using regulated voltage supplied from the battery, often 12 volts in most automotive applications. This power enables the ECM to control various functions, such as engine management and diagnostics, by processing input from various sensors throughout the vehicle.

What does the ecm relay switch do?
The ECM relay switch controls the power supply to the Engine Control Module (ECM) in a vehicle. When the ignition is turned on, the relay activates, allowing the ECM to receive power and communicate with other engine components. This ensures proper engine management and operation. If the relay fails, it can lead to engine starting issues or erratic performance.
Your ecm is not getting power?
Blown fuse, bad connection, or ground.
Why would the computer on a 87 firebird not flash codes?
It won't flash any if there aren't any to flash. It should at least flash code 12 when you use the test terminals. If it doesn't then you probably have a bad ECM. Make sure that you have power going to the ECM first. Most of the GM cars have a power wire running from the battery directly to the ECM. Make sure this is connected and the ECM fuse is good.
