It sounds like the battery is low on charge. We need to do some simple checks which this guide will help us with.

and if the engine is turning over let's check for ignition spark

This guide will help as well.

Please let us know what you find. I'm interested to see what it is.

Cheers, Ken

Try resetting security system if no manual look online. Then if it still doesn't start scan for codes and check fuel pressure with a gauge. Auto parts rent it.

Car made loud humming sound when I started the car. I turned off the car intending to restart it but it would not turn back on, I tried to get it jump started but that did not help at all. Right now I am without a car please help.

Does it crank(starter engage) at all. If not the starter may have stuck engaged explaining the humming noise, and this may have ruined the starter.
