I have a 2014 Hyundai Elantra. Pulled out of driveway and car stop in street. Crank but no start as if I'm out of gas. Tank half full. Is there a fuel cutoff switch? If so where? Need help

Check inside the trunk on the side of the fuel door. Most manufacturers make an emergency release handle for just such situations. It may be behind the trunk liner but should be on the same side of the vehicle as the door is.

The gas guage has a sending unit in the tank attached to the pump, there is a small circuit board on it that has smal"fingers" that send the signal to the guage.These get worn off and thus sends a false reading to the gas guage in the dash. The gas tank must be removed and a new unit put in to solve the problem. I had to do this repair to mine. As for the gas issue, just try pulling the nozzle back out of the filler neck when putting gas in, sometimes the overflow tube gets plugged up and won't allow the air to escape as the gas goes in the tank, making the gas pump think the car is full, pulling the nozzle will allow the air to escape. Hope this helps.

SOURCE: locate fuel filter, and safety switch to fuel pump

The filter is located at the rear seat, you have to remove it first, then you will see a cap attach with some screws. Inside that cap you`ll find the fuel filter. Before you change the fuel filter you have to release the fuel pressure first. To do that, first find the FUEL PUMP RELAY in the main fuse box located in the engine. Once you located open the fuel door and take off the cap and leave it open. Start the engine, take off the FUEL PUMP RELAY and leave the engine stop itself, when this occurs turn off the key, the you can take off the filter and changed it
