Gs300 sputtering when I step on gas

My lexus gs300 is sputtering like a real bad misfire when I step on the throttle like a quarter way down and I already changed the coils wires plugs and the fuel pump but after I put the new fuel pump it doesn't wanna start.

I had similar issue, mine turned out to be air intake leak at resonator. Check air intake to eliminate that as a cause.
