Gas guage/smell
 
Ever since the last time I fueled up, every time I start my car I get a strong smell of gasoline in the cabin for a few minutes then it subsides, also both the computers range number and the needle on the guage seem stuck, I did a round trip of about 150 miles today and no movement of the needle, and the computer range only went down a few miles, any ideas?

If it was the filler tube or a gas leak the car would tell you it detected a vapor recovery leak. Cabin air pulls from the same space you access the top of the fuel tank and the filler tubes pass through there.

The sending unit is the first thing you remove under the battery held in by the threaded cap. It has a float that moves with the gas level.

Fun fact! At 1/2 tank the top of the fuel pump is starting to show.

Best guess = small crack at the top of the fuel sending unit. Vapors get expelled when tank 1st pressurizes and then subsides once the engine starts.

Had similar symptoms and that's what it turned out to be.
