There are no "secondary" plugs, they all fire on the compression stroke.
I assume your tach is reading half as high as it should as well (idles at ~450-500rpm)?
You need to check to see which plugs aren't firing...easiest way to do so is when the car is off, unplug the front coil (all the plug wires go to the coils). Unplug it where the wiring harness plugs into the front of the coil, not unplug each plug wire. See if it will still start. Now plug it back in and unplug the wiring harness from the rear coil (it's at the back of the rear coil). See if it starts again. If it starts both times but runs bad, it's the ignition module, if it won't start, it's one of the coils that's bad.
all i know is 4 out of the 8 pulgs fire 20Degrees retarded and those are the only 4 that fire i hav done a ton os spark test and anything you could thing of to find the problem
