My 1992 Ford Ranger will not start. on 1992 Ford Ranger

I have replaced the distributor cap and rotor, the coil, and the ICM (Ignition Control Module) and I have checked for spark and am not getting any. I have even checked all fuses in the Power Distribution Unit and everything is good. The only other thing I can think of is the ECU (computer brain) is at fault but I am not sure where that is located. Can someone let me know or give me other possible reasons this isn't starting. And before anyone says this...."Yes I have check to make sure there is fuel getting to the system"

could be the distributor pick up coil inside the distributor which was a common failure. i would also verify there is 12 volts to the positive side of the coil to make sure the ignition switch is working.
