98 gas leak
I have a 98 UCF20 230k miles sometimes when I start the car it will smell like raw fuel and you can actually see it dripping under the car from between where the exhaust goes up to the engine. I can cut the car off and start it back and nothing will drop. It's very intermittent only does it sometimes. I have checked everything that I can possibly reach under the hood and nothing smells like gas. Any ideas?

Nice pic. The parts labeled 23270 might be good candidates for close inspection.
Also, this post (for my '91, I don't know how similar the newer cars are, but hopefully something close):

Shows how you can basically hot-wire your fuel pump (just a paperclip will do it for these purposes) to run continuously so you can have the system staying pressurized while you search for the leak - no need for the engine to be running or hot.
Fuel leaks are usually rare ... because cars don't last very long if they exist.
