car started stalling and now wont start.

It's possible that the fuel pump or the fuel pump relay have failed. The fuel pump is accessable through a service port in the floorpan above the tank. You could get in there with a meter or testlight and see if there's power and ground at the connector. If so, and you get nothing from the pump, it's failed. I think that's the most likely event. If you don't have power at the pump, then check the fuel pump relay and fuses. If you need a Mazda specialist, here's a directory link for you: https://repairpal.com/mazda-repair-in-yuma-arizona
