My 2006 Dodge Durango turns over but won't start.

What is your question?

New battery, new plugs w/ .040 gap, new crankshaft sensor, newer camshaft position sensor, coolant temp. sensor looked good. It started on a really cold morning and has not started since. When i turn the key it turns over fine and even thinks about catching sometimes but never does. Fuel pump can be heard priming when i first turn key. Fuel pump was brand new approx. 1 year ago. I can smell fuel in the passenger compartment after my first try at turn over. I tried the on, off, on, off, on trick and could not get any codes to display.
