EFI ground

Testing the EFI system , high idle until I push in the clutch after 15 seconds idle returns to normal. I am not getting continuity between #5 pin to gnd, 16 to gnd, 34 to gnd, and no continuity from air reg and fuel pump pin test.I don't understand how other parts of the system work while 5/16/34 don't. I have the battery out because I don't want to toast anything but am I leaving the circuit open by not having it connected? trying to go one step at a time .Thanks
