1995 90 2.8L 5spd No Spark
 

Let me get right into the thick of this.

I have no single (pulse) coming out of the ICM (Ignition Control Module) while cranking.
Test light lights up on output side while not cranking. (Bright light)

I do have dim single (constant ON, not pulsing) on the input side while not cranking.
** Should the test light blink on the input side of ICM while cranking?

Replaced crank sensor (new)

Have tried 4 different ICMs (used)

Car will start sometimes. Usually only if hooked up to a charger set for 55amp/start boost. Sometimes will start with using jumper cables.
Brand new battery (1 bosch 1 interstate) tried both same results. But still no spark.

Car seems to crank a bit slow unless hooked up to charger 55amp/boost. But still no spark.

Any Ideas?

Thanks in advance,
Steve

<EDIT>
I tested the wiring for the HALL sensor key on engine off
Results:
brn/blk = 12v (supposed to be 12v)
vio = 5.02v (supposed to be 5v)
red/blk = 12v (supposed to be 12v)
