Hard starting 5 liter

Hey guys, My 92 GT does NOT like to start soon after I turn it off. When the car is cold (haven't started in a hour or so) it starts, runs, drives just fine. But, if I turn it off after a drive and then try to re start it, it usually is hard starting but does start and then runs normal. Then, if I turn it off for a second time after another short drive (like running errands) It WILL NOT start unless I let it sit for 15 minutes or more. When it won't start, it cranks like crazy and I can smell fuel. I have a few ideas, but I'm wondering what you all think. Please throw in your 2 cents.
