Default HELP!! What would cause an injector to stick open??

I have been chasing a huge miss since last fall. There is massive fuel being dumped (puddles on the garage floor) into the exhaust and it drowns out the spark. I verified this by putting new plugs in, firing up the car and the #8 comes out shiny and new (and wet) as well as the header tube being much colder then the rest. The fuel is drowning the spark out. So #8 it is.

I've switched the #8 injector to another hole and it didn't do anything. Still shiny new plug in #8. I am convinced it is the wiring but have gone through the harness and versafueler wiring and don't see anything cut or out of the ordinary. I'm running a versafuler and 72# injectors on a 95 TA btw.

The opti was just done last month so that should be OK.

What in the wiring would cause an injector to stick open. I am getting 11.55V from the pink wire on #8 and all the wires on the driver side for that matter. The ground wire looks fine. Is there another ground I'm missing??

Any ideas??
Thanks

I'm not getting any DTC codes either but I am seeing "Injector fault" under the (binary) status bit display with TTSdatamaster.
