car repair on a 1998 ford contour svt?

[mela26]

I have a ford contour svt and it will turn over but will not fully crank up. Spark has been tested and it is not getting spark. We have replaced crankshaft sensor and that did NOT fix it. The check engine light is NOT on. The wiring that goes to the crankshaft sensor and runs across the motor looks bad the coating on the wires falls off and the wires are sticking together. I am not sure what this wiring is called. What could be my problem and what is the name of the wiring i am referring to. Please serious answers
