Afternoon,
If the temperature sensor is telling the ECM that the car is hot, it will prevent starting. You would have to have an ohm meter or scan tool with live data to see it.
If the crank or cam sensor is failing, the ECM will pick up on it in majority cases and set the MIL light. Without and ohm meter or scan tool for live data, you could check to insure they are connected tight and no loose wires on the plugs.
If the idle control motor is sticking, hard start will occur. You can remove it, clean it with throttle body cleaner and re-install and see if it improves.
High alcohol in the gas will cause poor starting when warmed up as well. NO E85 GAS, especially in cold weather conditions.
Check your grounds and battery output.
Other than that, it would have to be hooked up to a scan tool that reads live data to see what it is.
The crank sensor should be between 800-1300 k-ohms testing between the pins; camshaft, no ohms measurements, you have to look at the waveform pattern.
