Which one should you use?
You should use no fui yo to deny a specific completed act, such as breaking a vase. In contrast, if you want to deny a habitual behavior or a characteristic of your personality in the past (for example, saying 'It wasn't me [acting that way]'), you would use no era yo.
Is it said differently in some regions?
In parts of Mexico, the informal phrase No fui yo, carnal can be used to say 'It wasn't me'.
How does it change in a sentence?
The phrase no fui yo uses the preterite tense to refer to a specific completed action in the past. If you are adding a relative clause to the end, such as 'it wasn't me who…', use the structure no fui yo quien… followed by a third-person singular verb.
