I agree, the $20 set are probably junk. I recently posted about changing out a bad injector with a newer 4 hole injector. I swapped them out today and the engine runs great, even though it doesn't match the other 7 injectors. I bet the injectors are all stuck closed or have some other problem with them. Did you ask the seller why he/she was selling them?

Are you sure you reconnected everything?
