In need of desperate help.........

Having a diifficult time getting the car to start in the mornings and basically when its cold starts cutting off and misfiring there after when warmed up it seems to be fine

If the temp gauge goes up to 90 and the fan comes on, that would suggest that the temp sensor is OK.  :-\

Sounds more like an ignition problem to me. Have you checked your plugs and leads?  :)

Desmond has single coil pack... worth taking that out and checking the plug wells for water, as that could evaporate once warmed up. If plug wells are dry then the next stop weould be the coil pack itself :y

Nope, ecu and gauge sensors are two totaly seperate items.

Fan switch is seperate again and rad mounted.

Only sure way to check the ecu temp snesor is with live data and a suitable scan tool.

A good example of why I seldom dish out mechanical advice!  ::)  ;D
