Hey Marcel,
<p style=”text-align: center;”>Ive tried some known good pumps and no luck. I THINK the bike might have killed a ground somewhere. The connector to the fuel pump relay is definitely switching 12v over to pin 4 (measured between 1 & 4, orange & black) when you hit the killswitch. I do get ground from pin 1 & 3 (red and orange) to the battery ground but the relay never seems to pop. Neither does the Main Relay. Im hoping this isn’t ecu related and is a failure somewhere else.</p>
