MSPNP2 Crank no start

I've been a Nissan tech for many years but new to a/m ECUs and tuning. Trying to dip my feet in with a MSPNP2 made by Greg Lee. I have a 91 with a 94 1.8 swapped in using Flying Miata's conversion kit. Running 1.8 injectors, headers, and some crappy intake tubing to my AFM. I've already tried Google and the search functions.
Installed MS2PNP, loaded base map that came with it, changed injector size, changed spark mode to 4G63, offset timing by 8 (I'm running at 14 degrees 91 octane), pulled ST Sign fuse. Car cranks but doesnt start. I tried leaving the offset timing at 0, tried leaving spark mode on wheel, tried jumping fuel pump to ground (thinking I possibly broke the fuel driver), tried manipulating throttle. Wired up my AEM Wideband but that didn't change anything. I plug stock ECU back in and car starts fine. Attached are my datalogs with and without FP jumped. Any help is appreciated.
I think my next step is to set timing back to 10 degrees and check for spark.

I am going out of town for a couple days. I will open the box up to take pictures when I get back. I've attached 2 msl (one with my fuel pump jumped and one without) and my current tune
