No, you should not apply primer over paint. Primer is meant to be applied before painting to help the paint adhere better to the surface. Applying primer over paint may not provide the desired results and could affect the overall finish of the paint job.
You didn't mention whether you were using latex or oil based primer and paint, but generally the point of using primer is so that you can paint over it with any form of wall paint. Just read the label on your primer can to make sure it is compatible.

When trying to paint over an existing coat several factors need to be taken into consideration. Specifically, is this merely a second coat over the first coat? Is there deterioration in the paint?

Is the new paint latex? Is there any bare drywall? Unless there is something that we don't know, I would just buy enough paint to paint the wall 2 coats. If you want to prime it, you can have the primer tinted a little to get you closer to the color that you have chosen, but it will be more trouble and work than is necessary.
