WOW! Horrible Fuel smell!! 2006 Navigator 5.4l

I have noticed a bit of hesitation and a bit of shaking lately. A check engine light came on and went back off with no code stored in the computer. I noticed a very very strong fuel smell when driving today so i lifted the hood when i got home and it was still there. I crawled under the Nav and an exhaust clamp was wet. I wiped it with my finger and it was unburned fuel. Well, I had the Nav lifted in the front, which had fuel leaking out of the muffler. Any ideas?

Take it to AutoZone to see what codes are there.

I have a scanner. There are no codes. From what I have heard the codes for an issue like that are so generic, they aren't helpful.

Could be to high fuel pressure. You can also try cleaning the MAF with MAF cleaner, but that usually cause poor running.
