I=20 think you were wise to split your injectors power like that, I = did not=20 do that and in hind sight wish I had for the reason you=20 cited.

So do you get = the=20 6.5volts when both injector CB are = pulled?

When I turn = on the=20 P.injector switch ON, the EM lights up and I get 6.5V Voltage = reading and=20 "Low Voltage" warning on the EM2 display.

Ok, so there is power to your primary injector = switch=20 since the CB is not pulled.  In that case, I suspect that your = EM2 is=20 sensing the "sneakcircuit" voltage from your EC2.  I can think of = two=20 things to try depending on how much trouble each is to = do
 
1. Disconnect the primary CB from=20 power
2. Disconnect the Ec2 from the = EM2.
 
If easy to undo, I would disconnect the EM2 = from the EC2=20 - that way it either shows that the source is or is = not the=20 EC2.
 
If the problem goes away when the two are = disconnected=20 then I am convinced its the sneak circuit of the Ec2 feeding the=20 EM2.
If the problem does not go away then the only = thing I=20 can think of is a ground loop of some type - a bitch to try and deal=20 with.
 
 
 
and see the results of each on the = problem.
