"estaba and fui'
is there a difference between estaba and fui. I thought they both meant 'I was or I went'. Are they interchangeable?

estaba is of ESTAR (imperfect form)
fui is of SER and IR (preterite form) [yes they use the same preterite forms]
You can use the conjugator for that, but those are two different verbs, fui is preterite for ser and ir, estaba is imperfect preterit for estar, so no interchanging is possible there
