I'm having the exact same issue! I've replaced the CPS, and swapped the ASD relay as well. No fire coming from the coil. Sporadic voltage to the coil. I'm gonna try replacing the coil. (I have a spare)
The distributor shaft has a lot of play in it, and I'm wondering if the Camshaft position sensor in the distributor may be bad and causing the PCM to not send a signal to the ASD to power the coil.
