Engine Performance problem
2000 Cadillac Deville V8 Front Wheel Drive Automatic 177000 miles
This car runs fine when the temp is above 32 degrees. When it gets colder it will crank but will not fire or start. Just cranks. Someone told me to check the coolant sensor. So one night when it was only -7 degrees I tried to start it. Nothing. So I poored hot water in to the coolant tank. It started right up. SO then I took the tank out and cleaned it. Decided to leave the sensor unhooked. The car started fine, but the dash said to check the coolant level. Left the sensor unhooked. Yesterday morning tried to start the car, just cranked. Took a wire and jumped the sensor plug, still didn't start. Unhooked the jumper wire and it started. Am I looking in the wrong place or does the sensor have to be hooked up for the car to run?
have the same problem?
