Wont start has good battery

We really need more info to be helpful, like when did this start, any problem symptoms before it broke down, any work recently done, any engine DTCs, does it try to start like “put put put” then die?

An engine DTC reader or diagnostic trouble code reader could be very advantageous to see if there are any registered engine trouble codes that could point you in the right direction.

If the car doesn’t start but you think the battery is good. You need to first systematically check fuel, air, and spark to ensure your engine is getting everything it needs to start and run. Take extreme care when doing anything related to fuel and keep fire safety equipment handy. Once you pinpoint what is lacking, you troubleshoot further from there to determine what component of the fuel, air or spark delivery systems is not functioning.

Please let me know if you have more information and I will do my best to provide further assistance.
