just an update to let you all know.......i put my car in the shop and as of today they have no clue whats up. they told me the computers reading the fuel pressure regulator having issues but also the knock sensor is acting up. the mechanic said its almost like this pump is putting out a lot of gas and the fuel line cant handle it. its actually flooding itself. we're gonna replace the fuel pressure reg tomorrow and go from there. he's completely baffled as to why the knock sensor is acting up. im lost here too since all i did was replace the fuel pump w/a bat issued OEM pump and now this. who knows.......
