Small sidetrack: I had a friend die may years ago because the clutch switch preventing start in gear was bypassed. That's a fine option for troubleshooting but that's about as far as anyone should take it. I don't even have the switch bypassed in my Spec Miata race car.
Have you tried Jump starting?
Battery Voltage? (Healthy battery around 13V)
These batteries can work like nothing is wrong then nothing without warning
