fuel injector issues and help.

[2.2 Turbo]

Ok so first thing is, how do the injectors work with no ground. I had my t1 injectors in and the ground wasn't hooked up, but my car still ran. So finally got a hold of some t2 injectors, went to put them on, this is when I found that the ground wasn't hooked up. So I took the rail off hooked up the t2 injectors, and this time hooked up the ground, now here's where my other problem is, I put everything back together, and I won't start! You hear it kick over like it wants to start. But then it just floods out the spark plug. I know this cuz I took out th plug and it was wet. So is it to much fuel now, or is it just working better cuz the ground is hooked up? I don't know, just see what you get from this and give me some suggestions. Thanks

Power to the injectors is constant from the ASD relay, the controller controls the ground side of the injectors.
Obviously the T2 injectors are allowing to much fuel for the vehicle.

So what's the two wires that have one eyelid on them and there apart of the injector harness and it looks like it should be grounded?
