MERLIN2021 says: What you need to realize is that cars with fuel pumps in the gas tank need fuel to cover the pump, or overheating and pump destruction occur, it's a good practice to keep at least 1/4 of a tank so the pump stay cool, check for the fuel pum starting when you turn the key to on, it should run for 2-3 seconds.

Okay, so pretty much keep half a tank left in the car at all times. What kind of sound from the pump when starting am I listening for for those 2-3 seconds? AN actual pumping sound or hissing sound or air pressure sound? Will the car be able to start if I put more gas into the tank? Or do you think I've blown the pump because I drove it while it was too low on gas? I have yet to go back and try to start it again after it has been sitting since Thursday (b/c it's not at my house). I just want to make sure I am not spending money I do not have for towing and on a new pump if I do not need it and the problem can be solved by simply not driving down the gas past a half a tank. But after sitting for so long, is it possible it will start up again, at least enough to drive 4-5 blocks away to the gas station?

You should be able to actually hear the pump run from the gas tank take the gas cap off and have a friend turn the key, if you hear it, check for spark, here's how to test fuel pressure, and spark.
