Fuel Injector problem

I just want to verify this before taking apart. So I replaced all my injectors when I replaced my timing chain about 4 months ago, and last week my 94 Bronco started having problems, with hard starts and when I did get it running it was pushing out raw fuel out of the muffler like dripping out pretty bad.
So I hooked up my fuel pressure tester with the key on engine off and I had good pressure then it would drop to 0 within 4 seconds. so I started looking at my injectors for stuck open and so I unplugged all data feeds from injectors and found with my camera that I had fuel injectors leaking fuel in the cylinders with no data feed connected. I just want to make sure with key on and engine off It should hold pressure for a long time, right? The injectors shouldn't mist with no feed? and the rail should hold pressure am I right? or am I overlooking something?

No you got it they should not leak. Were they new, refurbished, or used?

Refurbished, from this place on ebay, Ive lost faith in this place now. I've only had them for 4 months, where should I get my next 8 or what do you think the best road to take is? I see 3 that are leaking maybe 4. WET spark plugs and right when i start it fuel is dipping out of the muffler. where is a good place to buy or brand?
