Leading coil failure

So I can't get my engine to start...

I have ran a diagnostic and my leading coils are recieving no spark. My trailings give off spark though so that's a good sign. So I figured my leading coils were bad, but I replaced them and it's still the same deal. I have checked fuses & connections.

Basically I think it could be grounding related. Any ideas? If you think it is a ground, where should I check? Note: I recently pulled my engine for repair and I dropped it back in so I coudl have missed something...

Okay, since I have yet to recieve any input I'd thought I'd comment that I got my leading coils to finally ignite after checking a ground. But they seem weaker than the trailing coils' spark when I compared them. Is this normal? Or what could be causing this now?

Still sounds like a ground problem to me. I'd say it's time to get out the sandpaper and start making the grounds bright and shiny.

Ground is everything with those things. you can test the new coil for resistance, to make sure they're good. But with minimal grounding you're gonna get minimal performance. BTW how about you tell us if you have any mods. Especially ignition ones.

The ignition system has not been modified. I'm a novice to the field of rotary performance anyways but I have a whole list of mods which is highlighted with a streetported 13B with a t04s 60-1.

I think I just made a dumbass mistake and didn't align my crank with the yellow timing mark. Could this be a problem?
