I have replaced coolant sensor and relay, fan still did not come on.So I used a wire to jump the sensor plug wire so the fan would come on when I turn the ignition key on then off when I turn the ignition key off.The fan would work then.

Hi,

If the fan will run, it's good. Also, since the relay was already replaced with the same results, that isn't the issue. I can tell you that if the relay is is getting power, then I expect the problem is between the ECM and the relay. The ECM is what signals the fan on.

Let me know.
