I have a 1994 MCM 5.7 with the thunderbolt ignition. I have no spark. My module is good checked it on a friends boat. I have 12vdc at the coil. I have replaced the coil,sensor,plugs,cap and rotor. I have ohm out the wires and they are good. The tach wire is not grounded out either. What am I missing?
