Timing (Jumper Isnt Working)

I am supposed to get a flashing check engine light when I connect the jumper correct? I connect the jumper by the kick panel but no matter what I adjust my timing to, the missfire does not go away and the car runs exactly the same whether it is full retard or full advance. Just bought plugs and wires, §§§§§ was replaced back in January. Cant think of anything else other then the jumper going bad or maybe my ecu?

What do you guys think? The forums arent helping me much.
