In the first post you said OE electronic ign. Is this the 5 pin OE ECU/4 terminal "dual" ballast? Pull the yellow wire off of the "ign" terminal on the starter relay to disable the starter and hold the coil secondary wire (dist end) 1/4 from the intake (ground) and seperate the zigzag dist pickup connector and drag the male terminal on the body connector half across the intake surface to make/break contact & see if the coil wire sparks with the ign key in "run" and have a helper hold it to "start" & if it sparks it points to the dist pickup/gap. Then take off all (might just be 1) wire from the coil neg primary and with a jumper wire with alligator clips on each end jump the coil neg terminal (not the wire you removed from it) to ground make/break like Morse Code (dragging it works) & same thing see if the coil wire sparks in "run" and in "start" if it sparks the coil/associated pri wireing is OK & points to the ECU or it associated wiring as the problem. Holler when you can
