Hold the coil wire (dist end) 1/4 from ground. key on. seperate the dist pickup zigzag 2 wire connector & drag the male tip of the body half of the connector across the intake to make/break ground & see if the coil wire sparks. Pull the yellow wire off of the "ign" terminal on the starter relay & have someone hold the ign key to "start" & redrag the connector & see if the coil wire sparks. check the reluctor gap in the dist (.008" with a brass feeler gauge) but "very close" is good enough for now. is this a 5 pin ECU/4 terminal "dual" ballast system or a 4 pin ECU/2 terminal "single" ECU system? Can you ohm your ballast for continuity?
