My temperature gauge doesn't work right when I first start my truck the gauge every once in awhile reads the actual temperature which is about 210 operating temperature but then shortly after within seconds it just drops and plays dead until I turn off and then start the truck again is this the sending unit the gauge or the wiring

Check the connection on the sender unit by the thermostat. Either that or the sender may be bad. If you plull the wire off, it should peg in one direction. When you ground it, it will peg in the other direction. This will test the dash unit.

So I need to ground the wire to the negative terminal on my battery and it should read at the hottest temperature and if it not grounded it will peg at lowest temperature and if thts the case tht means I need to replace the coolant temperature sensor

No, the temp sender unit. The coolant is for fuel control, not your temp gauge inside
