Engine Coolant Temperature Sensor

The Coolant Temperature Sensor is used to measure the temperature of the engine coolant. The readings from this sensor are then feedback to the engine control unit (ECU). This data from the sensor is then used to adjust the fuel injection and ignition timing. On some vehicles, the sensor may be used to switch on the electronic cooling fans as well. The data may also be used to provide readings for a coolant temperature gauge on the dash.

My engine starts only after gas pump is activate 1-3 min. before the start engine. If not I can not start engine. I changed the gas pump but the problen is not solved.

I just change my engine coolant sensor few hours ago due to engine cut off while running.because of error reading, the fan did'nt work and making the engine getting hot, jerking, hasitation and lastly engine cut off.never think that engine coolant sensor can do that far
