Then the Ignition Control Module probably is bad. That can be tested at an auto parts store along with the coil, but you already got a new one. Make sure the cap and rotor are good, Check the rotor on the underneath side of it in the middle, make sure there is no burn marks threw, if so that is the problem. The spark would be just going to ground. Check this before pulling the ICM.
