"Tu fais confiance à moi" is wrong? How so?

Bonjour Nicholas ! In the case of indirect objects - complements to the verb introduced by a preposition "à" or "de" - following the pattern "à + stress pronoun", in French they need to be replaced altogether by indirect object pronouns: "me, te, lui, nous, vous, leur". Here are links to our related lessons: Me, te, nous, vous = Me, you, us, you (direct and indirect object pronouns) Replacing people with lui, leur = him, her, them (indirect object pronouns) I hope that's helpful! À bientôt !
