code 43..? fuel pump sounds like sucking but still hvae 40psi
 

ok..recently i got a cel so i checked it after doing my swap..i'm pretty sure i got 10 and 43...i recently replaced the intake temp sensor thats fixed..
ok as for teh code 43..i dono whats goin on...
i bought a new fuel filter..my rail and injectors are working cause i checked them..
..i think its my fuel pump tho..when i get around a half tank or so..it sounds like its sucking up air and gas...its weird..is my fuel pump dieing or is my gas tank fucked up?
i have yet to run the car low on E or anything cause i'm sacred it won't even have gas...i'm reading 40 psi on my fuel filter..which makes sense..

any help me out please..
