Ok here is the low down:
I have raw fuel out of my exhaust
Checked all the plugs,the number 4 cylinder soked with gas
Unpluged the wire feeding the injector still smoking and raw fuel out of exhaust
Take the coil off #4 make sure it is firing, it is.
Take the v-band off the turbo start the car just for a few seconds soaked with raw fuel coming out of the rear impeller of the turbo
Mind u the injector is still unplugged
Checked oil no fuel in oil pan.
CAN THIS BE A STUCK OPEN INJECTOR?
OR maybe something else, im leaning towards stuck injector...

That absolutely sounds like a stuck open or very badly leaking injector. If you uninstall the injector itself and do a visual check it is usually pretty obvious is something is amiss.

I thought at first one of mine was bad so I pulled the rail with everything connected, and primed the fuel pump looking for leaks or bad oring.
