hey how are you

1- we need fuel & spark to start ? so what are you missing when it is hard to start ?

these mazda had issue with CKP sensor ,no spark causing this issue ?

2- do you hear fuel pump come on when it does not start ,if you tune the ignition switch from off to on ,it should come on for few seconds

Please let me know

Thank You
