Q: Car stalled and now won't crank

No start conditions are complicated to diagnose sometimes because of all the variables. This is especially the case in this situation where we have very limited information about what the vehicle is doing besides not starting. Questions such as: is it cranking normally? does it not crank at all? is it attempting to crank but does so slowly? do you hear any other sounds? what exactly was happening when it stalled? were you driving or stopped at a light? Answers to these questions can help point the technician in the right direction for a repair. My suggestion to you is to seek help from a qualified mechanic, such as one from YourMechanic. They will be able to ask you the appropriate questions, inspect your vehicle, and determine what is causing the stalling issue for your car.
