Check the IGN switch wiring

Question is, does fuel pump relay come in/ go out when ignition switched on? How do you know "no power source to fuel pump", was that because bypassing the relay didn't cause it to run? Or did you check for supply to the pump and find nothing doing?.
Sounds rather like a frozen pump to me... or a blown fuse??

Check your battery first. Cold weather does horrible things to car batteries... if it's more of a grinding sound I would say that your starter gear is bad. I believe they call it a ring gear? I had a similar problem with a kushman scooter that I use to deliver snowcones through the neighborhoods. It has teeth that need to engage and if those teeth have been grinded down it will have a hard time engaging....

If you hear the relay click, but no pressure at all then it would be the fuel pump needing replacement

First thing to check out will be the fuel pump relay under the hood. It is the one who drives the pump, so if it is defective the pump will not work either to prime the engine, or to make it run. Secondly, you need to check if the fuel filters are OK cause sometimes they clog up and prevent enough fuel from reaching the engine. Thirdly, check the injector(s) for cloging, and clean or replace them as needed. If none of this helps, then the problem probably has nothing to do with fuel delivery, and the next step to check will be the whole ignition system, which is also one of the most comon bronco problems.
Hope this helps?
