Project ls1 z32 Injector dumping fuel into # 3 cylinder getting sparkplug soaked+vid here are some videos of what the car is doing.

the problem is that when i plug in my # 3 injector wire the injector seems to stick open, or i presume its sticking open because its dumping fuel out of my drivers side exhaust manifold onto the ground. I purchased a brand new injector. and new plugs. all of my other injectors are working perfectly. i built my own standalone harness with instructions from lt1swap. im jw if it could be a wiring issue. do you know if its a grounded system or not? im really stuck and idk where to go from here. also like i said im getting fuel of course! too much atm. im getting spark. and i pulled the plugs and # 3 is the only one soaked in fuel. also was going to say that if i unplug the injector wire #3 it runs fine no fuel leaking but when i plug it in it does instantly start pouring gas out the manifold. its just weird that this is the only one giving me an issue any help would be awesome thanks!!
also can Text me at 605-695-5286 if that works too!!

The system uses ground to fire the injs.. If the #3 is open as soon as it's plugged in, then:
The inj is shorted internally. [Not likely w/ it being new.]
The grnd side of the plug is shorted to ground, thus turning the inj on 100% DC.This could be due to being wired wrong, or due to damage.
Time to get out the noid lite, the VOM, and start checking.
Noid goes on and stays on w/ KOEO?
