Weird coil trouble <--- help me please!

My car cranks, but doesn't start. I tracked the problem down to the coil. I disconnected the plug with the power wire (RED/GREEN) and when you turn the key in the ON position, theres is NO power at the RED/GREEN wire. But, when you leave the key on the OFF or ACC position, there is power!!! WTF? Like if my wiring harness was upside down.

Can anybody point me into the right direction, please. Thanks!

Check the red wire at a given injector connector to see if it acts the same way. If so, I'd inspect the EEC relay.
