NISSAN XTERRA ENGINE PROBLEM

2005 Nissan Xterra • 55,000 miles

I have a 2005 Nissan Xterra, with 55,000 miles. About a year ago, in the summer time, I replaced the Fuel Level Sensor in the fuel tank and everything has been fine since, with about 5000 additional miles.
A few weeks back during the bitter cold (-10 degress) in New Hampshire, I started the vehicle and drove out of the unheated garage about 100 feet, when the dash lights came on and the engine quit. I found that the fuel line at the fuel pump had popped off. I replaced the little blue snap plastic piece (called a RETER-QUICK CON), and made sure it had a snug fit, and was careful about the electrical connection, as well.
I went to try to start the vehicle (now 20 degrees) and after 10 tries, the engine still does not fire. I know when I did the Fuel Level Sensor repair, the engine fired after the second time of cranking, so I believe my procedure is okay.
Some things I wonder, why the fuel line popped off:
1. Would a fuel line pop off due to pressure, if a fuel line was frozen?
2. Would a fuel line pop off due to pressure, if something at the engine fuel system was locked up due to cold?
Now to get things going again:
1. How can I check to see if fuel is getting to the engine?
2. How can I tell if the fuel pump is working?

Fuel pressure test will test the fuel pum.

Yes, high pressure will do this but the line has to be frozen some where. Very odd if it is as gas has a very low freeze point. If the is water in the fuel or line, it will freeze
