I have a 2006 Saturn Vue. I had low gas and turned the car off for 10 minutes and then it would crank but not start and my gas gauge still reads empty after putting at least 5 gallons of gas in. I don't hear the fuel pump and my engine light is on, gas light on, and a car with a wrench through it on. I am trying to find a code reader because I have no idea what's wrong. The is no security light on either. A friend of mine tried using their code reader but kept getting just error. She said my battery doesn't have enough power but I had it hooked up to another vehicle for power. Any ideas????
