If your car runs out of gas, can you just pour gas back in the tank?

3. if the car is fuel injected

You need to get the gas to cycle first. The one time it happened to me, we tried to start it once it had gas and it did not start. We figured we would we cycle the ignition a few times. Once the gas was in the tank, turn the key to the "on" slot, but not the "start" or "run" slot. Its that spot where the electric works, but the car is not on. Usually the radio will work. Wait a few second, then turn it off. We cycled this a few times, maybe 3 or 4. The theory is that the electricity will engage the fuel pump, letting it prime the system. Then start her up. If it does not engage right away, turn it off and try again. Don't let it crank dry. Not sure if this would work for all cars, but it did for mine. We kind of made it up at the scene.
