CEL should go OFF any time crank is spinning, it means "ICM" is getting a good crank sensor signal/pulse and passing it on to the computer
So reads like crank sensor issue
Are you using the crank sensor and pulley(tone wheel) from the 1994 or 1999
They are the same sensor type, VR, and should be compatible either way
But CEL staying on means no pulse while cranking, so no spark
Make sure sensor is close to tone wheel, but not touching as wheel/crank spins
Yes, you can use oscilloscope, its a VR(variable reluctance) sensor, not a Hall Effect sensor
Loads of how-tos on internet on testing with oscilloscope
