I reread everything and you have a 4 pin ECU w the (pictured) 4 terminal (dual) ballast, correct? If so (1) see if you have continuity between the upper right and lower right terminals (disconnect both plugs & ohm it if you have a VOM) (2) see that the upper right (brown) terminal has fire when "cranking" & on to the coil positive pri terminal (3) that the "point" of the ECU pentastar connector has fire in "crank".
