With the injectors connected to the main buss, when ever there is power to the injectors they are OPEN!!!  This occurs even when the EC2 does not have power.  As I was trying to adjust my fuel pressure and check for leaks (there were only 4 ;-) I had about 10 min of pump running time with the injectors open before I discovered the issue.  Now I'm sure I have quite a puddle of fluid inside the intake and rotor chambers. 

Hi David,
 
I agree with Ed, and everyone else who said the injectors should not be open just because they have power on them.  Are you sure they were open, or did you measure 12V on them and assume they were open? 
 
Try this- turn the power back on to the injectors, and measure from each connection on the injector to ground with a voltmeter.  As Ed indicated, you should see 12V on both connections to show that the injector is off.  If you see 12V on one, and ground on the other, unplug the main EC-2 connector and check again.  If you still have ground on one side, you have inadvertently grounded the injectors in your wiring somewhere, which will cause an extremely high idle speed :-)
 
Good luck.
Rusty (I want to make noise again)
