Well, remember the Hall sensor is what tells the spark to fire. If that's bad it won't spark. Then the EZK module then does 3 things...
1) It tells the ignition amp to fire the coil & make spark. This is working.
2) It sends a signal to the tachometer.
3) It sends a signal to the fuel-injection ECU.
#2 & #3 are NOT shared along the same physical wire, that's why I asked whether the tach jumps while you crank the starter. Checking fault codes after cranking is probably the easiest way to see whether #3 is happening.
Also try this check...
Unplug an injector, or at least back-probe it's connector.
While cranking, you want to see +12v on one of the wires, full-time (I forget WHICH wire). If you don't, then maybe it's something easy like a broken wire from the main relay, or something else unrelated to the ECU. You've checked with a noid light, but you don't know which side of the circuit is not doing it's job.
