So I just finished installing my alternators and Walbro 255 twins. I go to check to make sure the pump turn on in ecm link and got nothing. The circuit that ran the inline works but not the dual hanger. I narrowed it down to the ground. The inline has its own ground, I was running the walbros to the factory ground on the harness ,the black wire. The factory hanger has provisions for a ground location . I'm using an aftermarket hanger so I was running the ground from the pumps to the black wire on car harness. When i grounded the wire elsewhere the pumps fired right up. . Where is this wire grounded too ? I've had the entire car apart ....
