From what I know, attempting to contact Lucifer himself is impossible (I have no idea why you'd want to do so anyhow). Perhaps a lesser being, but not Lucifer himself. If the old texts are true, and I'm remembering them correctly, he is sealed away by hundreds of seals, and these keep him away from the realm of men.
While I'm unsure of just how true that story is, I would recommend not trying it anyhow. If the Old Testament is correct, Lucifer hates all humans. But either way, there are more preferable ways to seek Truth than to risk speaking with demons. If you are still searching for a path to wisdom of the spirit, then PM me. I'll be glad to answer any questions you have.
