I have a 2006 mazda 3. Recently I went out to run errands and my car did not start. Their was no sound no dash lights just turning and nothing. Tried again same thing. On the third try the dash lights came on the seatbelt warning went dinged but still no start. On the 4th try the car started.
Since then it has started and will go for days then suddenly do the same thing again. This time it started for 2 weeks with no problem I replaced the battery and changed battery terminals as they were loose. I had the new battery checked and had the alternator checked both showed good. Any thoughts on what things it might could be?
