There is no fuel inside the tbi, is there anything like a switch that will prevent fuel from flowing if it is turned upside down? I took the intake off as one piece when I rebuilt the motor. It got moved around.

There is fuel up to the inlet of the throttle body the pump is working. It is something with the throttle body itself. Do you know anything about this tbi?
