Hello,

This could be due to a faulty coolant temperature sensor.
Malfunction in the coolant temperature sensor can send error messages to the ECM, then the ECM can think the engine is 'too hot' and won't allow it to start.
The temperature sensor works by changing its internal resistance as the temperature goes up or down. When it goes bad it can read higher resistance value, which can lead to the no start.

I have included the coolant temperature sensor testing guide for your reference. You will need a multimeter to perform that test.

Please let me know of any questions.
Thank you.
