Firstly whip out your thermostat, tie a peice of string around it, and the other end of the string round a pencil. The put the pencil across a pan or cup of water so the thermostat is suspended in the water. Heat the water. The thermostat should open between 65 and 85 degrees. If the water begins to boil before the 'stat opens, you need a new one.
If the thermostat is fine, change the temperature sender, and see if that has any affect.
If you have an ultimate engine steady fitted it maybe less trouble to change the sender first.

warm the engine up and switch the heater and fan on inside the car,
if you get heat and it stays warm your pump is fine, if it goes cold and stays cold then there is a good chance the pump is not working.
2nd check the top and bottom hoses, run the engine until warm and switch off
both hoses should be hot, if one is cool and the other hot then chances are your pump does not work.
If after tryng both of above you still think it is not working, take the main HT lead off the coil so the engine does not start.
Then take one side of the hose off the pump and turn the engine over a few times
you should get water pumping out.
If that does not work re-connect the hose and dis-connect the other side and try again, no water pumping through then would recon your pump is away.
