Default Not getting spark

I have a 96 z28 and I'm not getting spark but I don't want to start pointing fingers towards it being opti. My car started running rich and it fouled the plugs so I replaced them and was making plans to fix the running rich but a week after i put new plugs in I was driving it and I started stalling and back firing really bad and after the 5th time getting it to start I got 25ft and it shut down and it wouldn't start, it fouled my plugs again so I replaced them again but it doesn't have a spark. I have 12 volts going to my opti from both places that plugs into it (opti). Is there something I should check/over looking or am I screwed and have to replace the opti. Thanks in advance.

Not sure about the running rich problem. Could be a bad O2 sensor. For the no start issue it could be the icm. Check shoebox's site for details on how to check the icm and opti.
