On most vehicles, the coolant temperature sensor (CTS) can be found somewhere near the engine thermostat, which allows it to function optimally. The tip of the CTS is probably located right next to the engine coolant.
What problems can a bad coolant temperature sensor cause?
A faulty sensor can cause the fuel mixture to adjust. This causes the engine to shake or vibrate when the vehicle is at low speed and can even bring about strange behaviors, power losses, etc. Engines are highly sensitive, especially to inappropriate air-fuel mixtures at idle.

Can a temp sensor affect engine starting?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
Is there a fuse for coolant temperature sensor?
There isn't one per se. There will be a fused wire with voltage to the instrument cluster (your owners manual should indicate which fuse), but the temperature sensor is providing a variable "resistance to ground," which the temperature gauge in the dash is reflecting.
