P0125 - Insufficient Coolant Temperature for Closed Loop Fuel Control...Possible causes; Low engine coolant level, Leaking or stuck open thermostat, Faulty Engine Coolant Temperature (ECT) sensor, Engine Coolant Temperature (ECT) sensor harness is open or shorted, Engine Coolant Temperature (ECT) sensor electrical circuit poor connection...The voltage sent to Engine Control Module (ECM) from the Engine Coolant Temperature (ECT) sensor is not practical, even when some time has passed after starting the engine. The engine is taking too long to reach the normal temperature level.....P0118 - Engine Coolant Temperature Circuit High Input...Possible causes; Low engine coolant level, Faulty Engine Coolant Temperature (ECT) sensor, Faulty engine coolant thermostat, Engine Coolant Temperature (ECT) sensor harness is open or shorted, Engine Coolant Temperature (ECT) sensor electrical circuit poor connection... An excessively high voltage from the sensor is sent to ECM. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) P0118 Description The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.

Need some details on that, like does it turn over? If so is there spark? Proper fuel pressure? Just the basics of the problem.

Oil burnt? Check the compression of the cylinders. You may have no compression.
