injector good, wont stop spraying

If you have individually fired injectors, it's most likely the PCM (computer). The driver has failed.
If you have a batch setup, it's wiring -- because the other injectors fire OK. It COULD be wiring with an individually fired setup, but probably not.
If it is the PCM, you should probably still get the injector checked out. It may have overloaded the drive circuit and caused the failure in the first place.
Good Luck,

constant voltage at injector plug
I pulled out fuel rail turned key on and that one injector would not stop spraying. I switching the injector and that same thing happened. I have constant voltage at that injector plug, I think its only a few volts. I have an anolag meter it was set to 2.5 volts. The key was not on. I don't think its the wiring because there's no place it touches the engine. PCM then?

If you have power to the injector and a short to ground on the other wire the injector will always stay open.
Test ohms to ground on the 'cold' side.
A lot of good info here; Fuel Injection Technical Library

short to ground
Means that the power source to the injector is not there. The PCM grounds the injectors, so it is looking for a feedback signal, and when it is not there it will set a fault code. You will need to determine where the injector is getting it's power supply and correct that issue.
I found this on the net is this a correct statement? I have constant power at connecter, with out key.
