i have rc 440 injectors and i was woundering if my stock fuel pump will push enough fuel for my engine, and also would i need a fuel pressure regulater , also i will be runing hondata . the engine is in a 94 accord all motor fully built

 

you should be fine with the stock one, but since its a built motor why not just get the pump and regulator to have them for future upgrades. it would help to have the supply from the pump and the adjustability of the regulator for tuning.
