1995 Jeep Cherokee Problems!

I have a question for y’all that I am at a loss about. A friend was working on a 95 Jeep Cherokee (4.0L auto) and grounded out the Coolant Temperature Sensor trying to make sure his dash lights worked. Now the car will not start, it will however crank. He said when he grounded the sensor out, he heard some “clicking.”

check fuses under the PDC in the engine room and inside the car; I hope he did not fried the ECM…
