Hi there, I am Cam.Given your system is meant for the old sensor and such, you need to use the old ICM, old Sensor and see then if you get spark. The wiring for the new sensor to new ICM may not be compatible with the old systems.Can you try this and let me know what you find then reply back?
The 3rd wire is usually a ground shield wire. Try it and see then reply back to me.

At your ICM, do you have power on the pink wire and ground on the black?
Ok, the wiring to the crank sensor, what is the resistance over the 2 pins?
Ground shield its the third, so it should have resistance over the outside 2 wires.
Yes, but did you transfer all the wiring harnesses, sensors and modules from the old engine to this one?
You need ALL WIRING, COMPUTER AND SENSORS from the original engine to make it work.
It troubling when parts are mixed up, wiring may not match, computer systems different. Change them out and let me know what you find.
