HELLO, i'm new here...my name is david


I've replaced the sensor itself and I also replaced the temperature sensor sending unit..(both under the distributor)

Whenever I turn my car on it just goes from cold straight up to hot. I'm so confused why it's still doing that and I'm getting frustrated.. please don't rule out the cluster because that's my last resort..

PLEASE HELP

 

My first thought is that the sending wire is grounded somewhere. Maybe pinched? Or some insulation has come off?
