No. And 'bumping' posts like this would be a bit of a misuse of the site if it were possible.
If they question isn't getting any views / attention then that probably means the question itself isn't very good / clear. So best bet is to edit the the question itself to improve the quality, and make sure it's tagged appropriately. That will then push the question up to the top. That's the correct way to deal with these things.
If it's still not getting answers then perhaps people just don't know the answer. Constantly pushing it to the front of the queue isn't going to change things like that.
