Can you get sick from pricking yourself with a needle that has not been used?

Yes, it creates a portal of entry.

When the skin is pierced, it creates a portal of entry for microbes. Even though a needle that hasn’t been used is expected to be sterile, the act of pricking the skin provides a route for any contaminating organisms to enter deeper tissues. Illness is not guaranteed, but the potential exists because breaking the barrier gives pathogens an opportunity to invade. The key idea is that the breach in the skin is what matters for potential infection, not the mere fact that the needle hasn’t been used.

No, it cannot cause infection.

Only if there is visible blood.

Only if the needle was contaminated.
