Here’s how this works… you write sentences explaining your problem but you try to write complete sentences full of pertinent details. The idea is you want us to understand the issues involved so that we understand what’s going on and then we can try to help you.
“power drainage ecm circuit” fails on all of these counts.
Perhaps you can start over at the beginning and try again?
