KA24DE Fuel Rail Problem Please Help.....It would be greatly appreciated

[Brandondflt]

I have a '93 240SX SE Fastback with the KA24DE engine. The problem I'm having Im with the fuel is that its sending too much fuel to the engine and not sending it back to the fuel tank like it should which makes it sound like its misfiring when its really not......I talked to one of my friends that used to have it and he switched the fuel rail and injectors but still had the same problem....if anybody could help it would be greatly appreciated!!!!!

need to get a fuel pressure gauge and see what you get. may have a bad fuel pump or clogged fuel filter

Sounds like your fuel pressure is up to the moon.Check the fuel pressure regulator.

make sure vaccum lines are connected in right place on fpr, also, even though it sounds dumb, make sure the fuel return and sending lines are all hooked up right and not clogged
