Default wiring checks out

after drawing a diagram of wire moves I was correct. the acr;s and fuel pump become a series circuit. I pulled fuse from original fuel pump spot 4a-4b and fuel pump doesnt hum when I turn key on, put fuse back in and pull 3a-3b and same thing.
I checked purple wire in to emc plug ,it is in pin 19. dyno guy on weekend told me they are powered when the fuel pump turns on until it starts got 98 hp 107 torque
the only other thing to try next is unplug cord from ecm. run ground in pin 19 hole and listen if I hear solenoids clicking. If they work the problem will be the head clearance, these things are drilled right under the head gasket, I made a small groove back into the combustion chamber but now Im worried the acr nose may be screwed right down to the gasket. going to dealer to see if 103 or 110's use a different gasket, only problem is if they reshaped it to create a passage for escaping compression the gasket will be very thin on the outer edge.
