I recently purchased a 2005 Mazda Tribute with 27000 miles. After having the car for 2 weeks it would not start one Saturday morning. After the car was towed to the dealership is started up immediatley. They said it had something to do with the alarm but were not too clear. The following Saturday it did the exact same thing. Had it towed again and it started up immediatetly. Can't seem to find anything in the owner manual about why it would do this but again, I think it has something to do with the alarm disabling the car.
