So this maybe a repeat of a very common threaded discussion. This is my second Wrangler, My first 4.0 never had this.
I have a P0455 Code, Large Leak in the evap system I have put on an after market gas cap cleared the code still came back on. So I went and bought a factory cap, Cleared the code and back on.. I get a fuel smell as well during my driving and start up, I have 84,000 miles on the jeep. Not sure if this is connected to the upper issues but if I drive over 60 Miles constant driving I will come back out couple hours or over night and try to start it but it doesn't start right away. Takes a few more seconds than normal. I Looked over the lines but didn't see any damaged lines or connections on any of the hoses. Lost and confused!
