Can't pump gas into tank when the outside temp is below freezing
When the outside temperature gets below freezing, I am not able to pump gas into the tank. The hose immediately shuts off as if the tank is full. If I park it in a warm garage for a while, then I can pump gas.

I assume from the question that the engine is cranking over but will not start. Hence there is no issue with the starter motor on a very cold start.
At 40 degrees F you are getting closer to freezing. When this happens again I would check the operation of the fuel pump.
Take the fuel cap off the fuel tank and have someone switch the ignition on and off a few times. (just the ignition - don't start the engine up). Turn it on for 10 seconds or so and then off. If you listen at the fuel filler opening with the cap off you will be able to hear if the fuel pump starts and stops. If it is working it should start and then stop a few seconds later each time you switch on the ignition because the computer shuts it down in a few seconds if the engine is not started.
If the fuel pump is operating I would be looking for some electrical gremlins. You would need to check that the fuel injectors are getting power and that the spark plugs are also.
Ideally you would need to a quality scan tool connected to the car when you have this very cold no start condition whilst trying to start the car to see what faults may be present because it should pick up some malfunction if the start problem goes away when the temp rises a few degrees over 40F.
sound like transmission slipping.check transmissionfluid level if okay.change fluid and filter if its been long time since last change.when very cold out side let engine warm up get transmission fluid temp up.transmission fluid wont circulate too good if temperature way below freezing.new rule when cold outside let engine warm up get transmission temp up.
My 1986 Silverado 3/4 ton started that and I chased it, and chased it. Remember the KISS theory! Start with the fuel filter, because that what it ended up being. Can't explain why exactly, but when discussing it with other mechanics we came up with maybe some form of wax that would melt above a certain temperature. When the fuel filter fixed the problem, I removed the tanks and steam cleaned them and replaced, no more problems starting other than my chock needing adjusted every so often.
Your problem could be due to a clogged or gummed up fuel filter, usually when a car is run out of gas the manufacturer recommends changing the fuel filter due to the amount of sediment that inherently sits on the bottom of gas tanks and gets sucked into the system... especially one as old as this. Additionally you may have tank condensation that froze inside of your pump and it will need to be replaced. However this is a worst case scenario, always check the least expensive solution first.
Hi, this sounds like a classic case of your fuel is in need of canned heat, its freezing. If you didn't have the circulating heater plugged in, this will cause the battery to drain and the water and oil temperature to be cold and hard to turn over, but doing what is doing it sounds like you need to add more heat. You can put some in the tank and give your auto or truck a good shake or 2 and I have put some in the carb or intake if its fuel injected. I lived in Fairbanks Alaska for 10 years with temperatures at 60 plus below, and this is important. If you have done this, you could have a problem with the fuel pump being on the weak side, but I really don't think that's your problem. Let me know if you have used any gas heat or not. Shastalaker7
