There are two important issues being mixed together here.  One is the 
max current, which is important for sizing wires and fuses.  The second 
is typical running current, which is important for sizing alternators, 
batteries for alternator-out running time.  I think we have it all, but 
let's see:

                    Running@6000RPM        Surge
EC2                 .25A                   .25A
EM2                 .25A                   .25A
Each Injector       2A                     5A
Each Coil           2A                     5A

I've designed in quite a bit of electrical dependancy, so the 
alternator-out running time has me concerned.  With all injectors and 
coils on seperate switches, it should be possible to extend the range by 
switching off a set of injectors and the trailing coils, and accepting 
reduced power.  Does that sound viable?
