Crank sensor on 1994 Jeep Wrangler

No spark ,but I changed crank sensor and coil and still no spark.

Asked by for the 1994 Jeep Wrangler
Was the crank sensor or coil actually diagnosed or are you just throwing parts (guessing) at the problem? Is the ECM/ECU getting a signal? wiring problem? is the ECM/ECU sending a signal to the coil?
