Buzzer starts when I turn key to on before engine even starts. Started yesterday when idling, came home and still doing it today. When I turn key to on, All other lights flash for two secs and Alt stays on. I can start motor and all lights go off except green oil light. Engine runs fine. I've disconnected trim sensor under cowl, confirmed oil is good, drained water separator on engine. I've tried to pull ECM codes by jumping red connector under cowl, but Ecm light just stays lit when I turn key, it doesn't flash.
im stumped, any thoughts.
