How are the grounds on the intake manifold? Cleaned up nicely? Sometimes they can break inside the wire loom of the harness and look ok but actually be nonfunctioning.
As far as how I said for the O2 sensor and ignitor clips, usually the ignitors clip is closer to the coil clip. The O2 sensors one should be closer towards the front.
Do you have a volt meter? I would start going through things like the ignitor, coil, distributor, etc until I find something funny. My car actually would not start and I figure out I had some bad wires and weak power getting to parts.
