what is the problem?
 

ok we bought a 93 rx7 couple of months ago and we got it from auction and it was stolen title but when we got it the car started but it smokes with white smoke but it smells like oil. and another problem when i started the car i staled and the car wont start again we tried pushng the car and it started but it cant start by itself. when you put the key in every thing works but when turning the key to start it doesnt do anything. So i am new to this car and i need to find whats the problem if some one knows what to do plzzz write to me dima_b32@yahoo.com thanks

Maybe you can start by pulling code(s) to see if the ecu can tell you what's happened. If no information then it could be any number of issues. A compression test is a good place to start and work from there.
