Follow this procedure:
1. If the engine does not start within five seconds on the first try, wait ten seconds and try again.

5. If the engine fails to start, crank it without depressing the accelerator.
If the engine still does not start using the previous procedure, have your vehicle inspected by an Authorized Mazda Dealer.
