Car wont start shows -3-60 on the dash and check engine light flashing

Hello, don't pay attention to warning lights and messages, just focus on low battery voltage, which is apparent. Check the engine's battery and verify you have one that is fully charged and able to sustain a load. I'm willing to bet that you'll resolve your concerns once a good battery is present and installed, and your vehicle is verified to have no parasitic draws nor charging system concerns.
