orange splatter

Hey so I know this question has been posted a lot on various forums, however I haven't been able to fix my problem. I am running a tekkit lite server version 1.4.7 with 3 friends and we can place the quarry and land marks and have it make the red and black square defining the boundaries of the quarry, however no matter which engines we use, they won't do anything when powered next to the quarry. I know the engines work on other things since I have a working pump. I have opped [buildCraft] and buildcraft and have no additional plug-ins. Any help?
