the car will not start.cranks but no spark.coil is good and so is the crankshaft sensor.checked all electrical connections and fuses.the only code I could retreave was 0117-water temp sensor low input.what else would keep it from firing?

Try replacing the sensor. Some vehicles have a safety cutoff feature if the engine temp. cannot be read. http://www.autozone.com/engine-management/coolant-temperature-sensor/duralast-coolant-temperature-sensor/subaru/impreza-outback-awd/2000/4-cylinders-4-2-2l-mfi/233511_0_18589/
