not sparking properly

I have a 1998 cavalier z24. I am only getting spark for 2 of the cylinders, one isnt a strong spark. The other two not getting any spark. Had the ignition control module tested at autone and is ok. Ohmed the coils and they also checked out. The crank sensor is supposed to put out 5 volts but I don't get any voltage, bought a new one put it on, still nothing. Would the crank sensor keep the two cylinders from sparking, if not any ideas would be appreciated. Thanks
