O.k. If I am understanding you, no gas is getting to carb, but more importantly when you turn the key nothing happens except a few lights come on. I would start by checking the solonoid. It is a cheap part to replace and it causes a lot of problems, but first check your kill switches and inline fuses. I think that there is either a fuse blown or a switch that is cutting your power. Also double check to make sure that all wire connections are tight and not corroded. Make sure all ground wires are attached and clean.
