Present perfect will have "have -ed" somewhere in the verb phrase.

Past tense will have NO auxiliary verbs. I don't know how that would even occur in a sentence. Modals ARE a form of auxiliary verbs.

Present continuous will have "be" or some other present tense form of "be" plus a verb ending in -ing.

Future perfect will ALWAYS have "will have" somewhere in the verb phrase.
