rb25 ran fine, randomly quit starting.

[GeneralTso]

well my friend traded a car a while back for this rb25 swapped hatch. the car has ran fine and great for a month and it started acting wierd when starting a few days ago. we've checked all the grounds and replaced relays, made sure the fuel pumps priming, changed plugs, made sure it has spark & fuel, and we jus't cant figure out whats wrong with it. i'd appreciate any help. we don't have a shop within like 4 hours of us that fucks with imports so any help's appreciated.
