Follow fuel delivery first. Pull the fuel filter, pump the primer, see if you get anything there. If you're getting fuel at the filter base, slap a NEW filter on there, prime, and see what you get.
If not, bump the motor over and try again few times. If that doesn't get you any fuel, look for a broken/pinched fuel line, if none, the lift pump could be bad.
Good thing you didn't try running it on ether in cooler weather. The grid heaters will ignite it. There are two cables that hook into a block on top of the intake manifold, you should disconnect them before using ether when it's cooler out.
If the FSS isn't turning the fuel on, you will probably put a pull cable on it once you see the price tag.
Try posting about it over here.
