If you have access to a meter for 12v check for on off transitions with power & ignition on at the coil
With the key and ignition on,
voltage should change as you rotate the engine, plugs out and wires grounded. check from B to A and B to C
the coil is turned off to make a spark.
thats one test
visualy inspect the wiring from the ecm to the coil check for nicks and cuts
IF YOU CAN borrow a known good ECM and swap it out as the ECM controls the EFI and the ignition,
OH BTW if 12v not present AB BC check the ignition relay and the other switches / fuses .
