The ground for the coil side of relay is through the neutral switch. No ground, the relay won't energize. If you use a jumper on the left side of relay picture between red wire and brown wire, the starter should crank. You don't have to use the key. If it still won't crank, have the starter tested. Some of the national brand autostores will test the starter for you. Yeah, you have to take it off and take it to them.
Any testing at the relay, make sure the tranny is in park or neutral and the e-brake is set. I got nothing else, have a good day.
