out of gas?

well, when I got to the car, and turned the key, I noticed that none of the warning lights came on, as normal. I thought perhaps some electrical problem, fuse or ing switch, tranny switch, as I said, it turned over fine. Headlights worked, dash lights worked. So AAA puts in the gas, I tried it ,turned over but didn't start, turned key off and tried again, this time all the reg warning lights came on and it fired right up. So it confused me about the Warning lights, I'm asking if there was or is any relationship between the warning lights and being out of fuel. I don't know, however I don't think so. thanks John
