How to stop the sound the car makes?

Hi and welcome to FixYa,

Offhand, definitely an electrical issue. Some ideas to check, consider and/or explore:

• IGN switch - check for loose, corroded or heating connections. To test, under normal usage of the vehicle, should feel warm but not overly hot. If so, then possibly loose connection;
• fuse/relay box - check for loose, corroded or burned terminals, holders, clips and connectors/pins. Use an electrical contact cleaner and spray. It may also be necessary to scrape to remove burnt marks/corrosion;
• fusible link - the battery would have 2 wires connected to the + terminal. The big wire goes to the starter, the smaller of the two is the electrical systems main wire. This normally goes to the fuse/relay box. Check for frayed ends, loose connection, corroded terminals. In some instances instead of being at the battery's + terminal, it is connected to the end of the big cable down at the starter motor.
• ALL connectors with big wires - these carry the main +12 either as always ON, ACC or IGN. If a connector has a wire bigger than the others, check them. It may be necessary to disconnect to enable you access to the inside pins/terminals. Scrape them clean.

I had the exact smae problem and threw aaway a ton of money on bad "guesses" at what was wrong. The actual fix was replacing the crank shaft position sensor for 50 or 60 bucks. Swapped out bad for good and cars has run great every day since.

The fill tube for the fuel tank is either clogged with something or the anti-siphon feature (what stops people from stealing your gas) is fouled up. The tank and fill tube have to be inspected.

I have a 2005 Hyundai Accent, It is not possible to fill the tank if you are letting the petrol pump run at full speed.Trying to fill up quickly it will only build up pressure and cut off. Next time you fill up just pull the petrol pump handle half way, it will take longer to fill but you wont get the blow back. Modern petrol pumps are getting quicker all the time.Hope this helps you.

I had a similar problem and had an engine tune up done and the car runs almost like new now. Mine is a 2001 Hyundai Accent too.
