You can get the connector from ebay, you may still be able to get the sensor from ford?....

Thermo switch controls more than just the cold start injector. On n/a MFIs, it controls the cold start injector and the fuel shut off. In KE-Jets the ECU also gets the temperature from the sensor (it isn't a switch then) to control amount of fuel. So it should be connected correct to cure your hot/cold start problems.

Im pretty sure the sensor/switch for the cold start valve is only used for the cold start valve, it has a small heating element in it and a bimetallic spring, which can fail.

You may be referring to the engine coolant temp sensor or the air temp sensor.

Rob,
