We have air. We have spark. We have no fuel. It comes to life on starter fluid but then dies without even trying to stay alive. This car went from driving just fine (passed emissions) to not starting overnight. Not even trying to catch. Nothing.
There is new fuel in the tank. It's not leaking fuel (or anything else) anywhere, other than the requisite drop or two of residual oil. We don't smell fuel while trying to start it.
Where do you start troubleshooting for this?
