Have a civic1993 theres no power on fuel injectors

What is the model trim (LX, DX...) and engine? If your injectors have a Yellow/Black wire in common, check fuse 31 (15A)(Power for the injectors), your main relay or fuse 18 (7.5A)(Power for the main relay control). Does the main relay "click" when you turn the key to RUN/START? If you remove the relay, check to if one pin has 12v on it with the key off. Two other pins should be hot while starting. If you want a wiring diagram, reply with your email and I can send you one.
