fuel supply problem??

hey guys im new to this site and a buddy of mine told me if a wanted answers from people that know their stuff about preludes to come here..

so anyways i have a 93 prelude 4ws H23 with 248k on it i just got it not to long ago and recently it has started sputtering and backfiring only at low rpms and its throwing the check engine light on reading code 43 which is fuel delivery. so i did a full tune up on it and put a fuel filter in it and still no solution.
my question is could it be fuel injectors, fuel rail fuel pressure regulator or possibly fuel pump going out??
any one else having this problem plz let me know whag you guys think

yea still getting it but i figured out what it was.
it was the fuel pressure regulator so i disconnected the vaccum hose on the top and running it around like that until i get $70 to get a new one

Re: fuel supply problem??

when my fuel pump went it didnt give a warning, it just went i thought it was the battery because it started up one more time then BAM in the autozone parking lot it was done.. so i doubt it is your fuel pump (my dad was a mechanic for Honda 93-96 and he was with me and said what happened normally is how fuel pumps go) i would def check your fuel injectors..
