No Trailing spark

Getting no trailing spark anywhere. Ground the plug to the strut tower bolt and no spark. I have power from the coil, to the dizzy trailing plug-in, and then nothing out. Swapped ignitors with one from my other dizzy that ran fine, and still nothing.

Currently doing the 2GDFIS, and I am getting power and spark from my leading. This is really sucking because I never got the car registered and it ran great, then the trailing coil was going out (tach died) and picked up the 2GDFIS. Now the car is registered and plated, ready to go, but now it will not run. Currently deflooding it as well.

So does anyone know how to get trailing spark? I have the voltometer and its reading power everywhere but from out the dizzy to the plugs.

What is the yellow wire with the blue line on the dizzy harness for?

I think that is the signal wire that hooks onto the trailing coil.

I got the FSM and it says that the yellow/green is the signal for the trailing, but the yellow/blue is leading and that is what is cut... Oh well, I went ahead and ordered another one.
