Hello I will help you with your question,

The coolant temperature sensor is a problem on these. It is on the transmission end of the engine and has a yellow and black wire to it.

Do you have a voltmeter to read the resistance of the sensor and the power to the pump?

Inspect the connector to see if there is corrosion or coolant in the sensor and let me know on the voltmeter

Thank you

no voltmeter.. is the temp sensor expensive, or can it be jumppered to check.

If you are not turning on the pump then I don't think it is all in the temp senor (about $12) but you would be better off getting a voltmeter and I can guide you to checking the pump circuit and the coolant temp circuit. It means working when it won't start in the cold though.
