EFI relay is just a relay triggered by the IGN power, to reduce load on the ignition switch.
D3 just grounds the circuit opening relay when the engine is running (so it turns things off when engine stops), so if you don't have circuit opening relay, D3 doesn't need to go to anything, and you do not want to put it directly to battery power!! it likely needs the resistance of the relay coil to reduce the current going through D3
The Circuit opening relay turns on and controls the fuel pump (in above diagram)
should not need power to fuel pump to get spark.
the 4 igniters have 2 connections each. both connections come from the ECU
on my diagram, one set of connections comes from plug "g", pins g9, g10, g19, g20 (called ION1, ION2, ION3, ION4)
plug g is also called B47. this is plug B on your image link here

The other connection is on plug f, pins f10, f11, f12, f13. (called IGT, IGT2, IGT3, IGT4)
plug f is also called B48. this is plug A on your image link here

if you have plugs A and B connected, then.. should spark if it is getting the right rpm signals?
