I had this same issue once on a 1989 F-250. It's a longshot, but after replacing the intake manifold, a wire near the processor that went to one of the O2 sensors has mistakenly gotten undrneath the corner of the intake. This was enough to short out the processor so it wouldn't function. So, check all around for pinched, trapped or shorted wires, it only takes one. Another thing; is there a small ecm inside the distributor? These fail a lot. Also it is common for the pick-up sensor on the exciter ring inside the distributor to be weak and need replaced. This is essesntially a switch that opens or closes to send the spark signal. Good luck. Man it took me forever to find that pinched wire. Behind the engine with 1/2" to work. I found it with a mirror.
