No start - weak spark?

No start - weak spark?
Hi all,
I'm working on diagnosing a no-start situation with my 2006 G35 coupe. The car cranks but won't turn over.
My first thought was the battery, since that was going on 5 years old. I went ahead and replaced that with no luck, now I'm trying to be more systematic in identifying the issue.
I got a spark tester on one of the coils and it seems like the interval between sparks is a bit long. Here is a video of the car cranking with the tester. You can't see the sparks too well but you can hear them. Does it seem like the sparks are not frequent enough?
I hooked up a OBD2 code reader and there are no codes.
Depending on what you all think, my next steps are to either check if I am getting fuel pressure, or to work backwards on the ignition if the spark is not fast enough.
As a side note, would something like this work to check the fuel pressure? Or will I need an adapter? It looks like that one is for schrader valves.
