Hello,

This is an emission related code:
DTC P0496
Evaporative Emission (EVAP) System Flow During Non-Purge

You might not be getting fuel, that's why it does not start.

From what you are describing you might have gotten poor quality fuel. Many cases poor fuel quality requires all the fuel to be drained and purge the system before being able to fix the vehicle.
I have attached a basic diagnostics of poor fuel quality.

Let me know of any questions.

Thank you.
