Starting Issue

S14 motor with:
s13 dizzy, intake mani, ecu, wiring harness, maf etc
All grounds are on
Plugs are sparking
Fuel pressure seems fine last time i checked

I primed the cylinders individually and got a sputter out of it.
After the fuel burnt out, nothing again just cranking and wat seems like tiny intake popping sounds randomly when cranking

Also i have never heard this noise before, key left in ON position
listening in engine bay sounds like a pump priming for 3-4 seconds then stops and comes back on in a min or two…

whats the next shit to check

battery is good alt is good etc…

thanks in advance
