Is the connector still plugged in when you are probing the wires?

I don't have the wiring diagram with me now, so I might be confused...

The main relay supplies 12v to the injectors continuously. The ECU makes & breaks the connection to ground when it wants to fire them. So, if the ECU is NOT firing the injectors, you'll see 12v at both pins.

With the plug disconected, it should have voltage at one wire only.
