    I had it unplugged and 2 gymclips inserted into it with rubberized tape on it. Still think it could be it the sending unit?

    Why do you have it bypassed?

    I'm not sure what you mean by gymclip? But if that is just straight wired that doesn't work. You have to have the proper resistor in between them to fool the ECM. A coolant temp sensor is a thermistor.

    Yeah if it doesnt have the "right" reading from the temp sensor it will default and shut down, btw what type of oil do you use and when is the last time you changed it?
