First, I would like to ask you about this tense ( Past present simple ) are you sure it exists? Sincerly I dont know it.
Second, you can detect a past simple sentence by time markers that refer to the past such as: yesterday, last week, two years ago, in 2002 ...
Third, (used to) is an expression or a semi-modal that we use to talk about past habits that dont exist now, so it is alwyas used in the past tense.
I used to play tennis when I was young. It means that now dont. And the rule is: used to + infinitive
I hope I helped you.
