I just purchased an 04 rx8. I had the engine rebuilt and now I can't get it to start. We have tried everything! We got a new battery, changed the spark plugs, and we have been through three starters. We finally figured out that the starter was not big enough so we got the 06 starter and put on the car but the starter still won't disengage. What could be the problem?

 

Is the engine cranking and not firing?
