93 s10

Okay guys I'm new here and am needing some help with my 93 s10. So originally I replaced plugs and wires leaving my little 2.8l runnging like crap. So I replaced the distributor cap and rotor didn't fix the problem. It was running rough ideal and back firing. So I replaced the distributor now I have just cram king no start so replaced the cool still nothing. I have followed the instructions on how to install the distributor and to find top dead center. I'm at a loss if anyone has any ideas I would very much appreciate the feedback.
