Default S2000 Crank But No Start!!

Hello!
I'm a new S2000 owner and I'm experiencing my first major issue!

I have a 2004 AP2 S2000 with an AEM EMS2 Standalone ECU and an ITB setup. The other day when I was cruising on the highway, my gauges all dropped to zero, and my tach ended up getting stuck around 3000 rpm with my foot down. The car ended up dying and I haven't been able to get it started since.
So far this is what I know:

- The car is getting spark
- The fuel pump is getting 12V but still not priming. (Yes I've tried multiple fuel pumps)
- The main relay has been replaced
- MAP sensors are reading correct voltage

The car cranks completely fine, just won't turn over. No codes because of the standalone ECU.

Any Ideas? Thanks! )

think you already found it. Check your fuel pressure to confirm. You can try shooting brake cleaner into your air intake and see if it will fire up to also confirm it not getting fuel
