Stand along MSII on my 99. I have spark and can smell fuel. Cam and crank triggers seem to be correct and I have a tach signal. The motor spins over normally and sounds like it wants to start, I can even hear it firing but it just wont catch. I did nothing but install the MS.
Here are some screen shots of the composite logger. I also attached the log file and my MSQ.

I actually tried that but my battery was nearly dead. I'm going to try it again.

I'll have to look again, but I'm pretty sure it flashes back and forth from red to green while cranking.

Well my battery is/was really low at the time. I just picked up a charger so I can continue working.

I did nothing with any of that before installing the ms, the car ran perfect. Stock coils.
Yea and the weird part is that I made no Changes between the 3.

No, Brain would have to answer that one.

Okay, I've got the battery hooked up to a charger so I have full voltage now. I tried starting the car with the coils in both positions and no luck. The SYNC tab at the lower left stays green while cranking. I just checked for spark again and its good, I can definitely smell fuel and I am getting a tach signal. Here is another screen shot of the composite logger. I know there aren't suppose to be any spikes in the red line. So, what do those spikes mean?

I had the same problem on a customer's car - MS2 V3 board, circuit worked fine on the stim, it wouldn't sync properly on the car. Checked and found a few errors. Fixed them and it would sync, but wouldn't go past 5100rpm, even free-revving. Promptly upgraded the unit to a DIYPNP free of charge and I promised myself never to do a V3 on a NB again.
