If you dismantled the stepper motor then you now need a new one. They are magnetised after assembly and once they have been apart they will have very little power.

Stepper motors do that when they have one wire broken out of the four. It is where I would start, it's the easiest to check.
Just thought I would add that in case you didn't have enough to check...
