do y does son los auxiliares del presente para preguntar o negar 
do se usa con :I, you, we, they
does se usa con he, she , it
con el verbo to be y can no se necesita auxiliar, simplemente se hace una inversión del sujeto con el verbo
did es el auxiliar para preguntar o negar en el pasado,para todas las personas , el verbo debe estar en infinitivo

por ejemplo
He bought a new car yesterday    Él compró un nuevo coche ayer
Did he buy a new car yesterday?  ¿Él compró un nuevo coche ayer?
como verás , cuando pregunto, el verbo ya no está en pasado, ya tenemos el did que nos lo está indicando
