When trying to turn on the vehicle it did not start and none of the lights would turn on. I used jumper cables to get it to start but the fuel gauge read empty even though I knew it was not. Regardless, I put in gas and it was less than $15 so I know it wasn't empty. After dispensing the gas the fuel gauge read Full. Also, before I put in more gas, when I stepped on the gas pedal all the way down (while in park) it would not accelerate. It would maintain only a constant sound. After dispensing the additional gas though, the accelerator was fine. Could this be an issue with the battery (which is only 1 year old) or the gas tank? Any information would be appreciated. Thanks.
