Cavaliar start up on near empty gas level, died, added gas, then did not start

Alright so the catch is that it was -20 below outside (literally)

I own a 2000 cavalier

I usually keep my gas tank filled up to about a half tank during the winter months, but it completely slipped my mind one night.

I warmed up my car in the morning (it was 20 below), and it started fine. I then had to remove my keychain from the ignition so I could lock my house. I come back 10 seconds later and my car would not start. I suspected it ran out of gas, as the level was on empty (I live 2 blocks from a gas station). I then added half a tank of gas plus some heet ice removal and it still did not start. I suspect I froze my fuel line but that does not make sense since it started fine in the morning!? This happened yesterday morning and it still does not start

Do you hear the pump running? Is there any security lights flashing?

Being that it was -20 I would guess your from MN or NoDak. If MN the gas already has ethanol in it which absorbs moisture so the chances of a frozen fuel line are just about 100% zero! I've been in the business for over 13 years and have yet to run into a froxen fuel line as the cause of a no start. My bet is on the fuel pump. They are already a week component and rely on being surrounded by gas to stal cool. Run the tank to empty (more than likely a plugged fuel filter which also adds to the stress on the pump) and you leave the pump suseptible to overheating, even in -20 degree temps.

I would guess you have at least 80k miles on it? This is about the average mileage for the first pump on these. You'll get way more miles with frequent (every 30k) fuel filter changes and keeping the tank at least 1/4 full.
