My 83 280ZXT runs like **** after I start my car this morning. I took off spark plug and check for injector, I can not see any gas get from it. I can see gas spray out last time I check it. But this time it just !#@[email protected]%^&*, anyway I also check thr pressure in the fuel line it's fine, it looks to me like the injector didn't fully open. It's two wire go into injector, both of them are +, where is _ current come from??, also whick component control injector?? If you know what's the problem I might have please let me know.

Thanks in advance

Sounds like you're pretty frustrated.
Check all of the connections to the injectors. They often become coroded. Also if the injector is stuck open or closed, you may be in for a set of new ones. I saw this happen on a Chrysler Conquest TSI. Those only have 2 injectors and one of them stuck open. Consequently the motor flooded instantly. Maybe one of your injectors has stuck shut. If this is the case, a good cleaning may free it up. I know that some NAPA auto parts stores can service injectors. Good Luck!!!!!!!

Don't forget to check the cold start valve connections while you are checking the other injector connections.

A Turbo car doesn't have a cold start valve. The computer switches the neg, thereby firing the injector.
