Cold weather starting problem


I would say it's bad contacts in the ignition switch. Metals change dimensions depending on temperature, looks like 45 degrees is the trick point for whatever is in there. My 04 Silverado 5.3 with 196,000 has the ticking, but it is gone within 10-15 seconds.

99 silverado wont start when below 35 outside when it hit 40 outside it starts and runs fine ????


First place I'd look is at the coolant temp sensor. If it's out of range the computer will not know it's cold out and therefore will not demand the amount of fuel necessary for a cold start.

1999 chevy silverado 4.8 1500 will star but not idle


Could be as simple as your fuel filter...after the truck starts..can you keep it runing by gunning the motor?

If you can feather the accelerator to keep the motor runing, I'd start at the filter, and then check the fuel pump

Water temp gauge stay on 160 degree


should be fine as long as the gage goes up and down and you get heat it should be fine make sure you consider the outside temp. as the engine starts it will heat up get really hot the the thermostate opens and the gage will fall and should but not always stay low it could just be the ip gage.
