    2000 Silverado won't start in cold weather

    About a month ago my truck would not start on cold mornings. The engine would turn over fine but seemed to not be firing. After replacing the Temperature Coolant Sensor truck started with no problems for the last month. This morning was a very cold morning and my truck would not start again. Engine turns over but does not try to start. No sputtering, nothing. Codes have been checked and nothing is being reported. I can hear the fuel pump run when key is first turned on. Any help or suggestions would be greatly appreciated.

    Did you check codes or have a proper scan? Scans are better because they show weak parts that don't throw codes. temp sensors are a common problem for cold starts, but it sounds like a good scan is needed

    You should check the fuel filter.

    Codes were checked, no scan done. Fuel pressure was checked last time and it was good. Fuel filter was checked to see if it was flowing gas and it was good. Will replace coolant sensor again tonight.

    After a scan was completed. The distributor cap and rotor were replaced. Appears to have taken care of the problem. Truck is running better too. Will also replace the ignition coil. Thanks for the all the help.
