99 jeep GCL v8 4.7L won't start but will crank. No CELs. There is one that pops on while trying to start but goes away after about 5 secs too quick to check. Just changed spark plugs last week. While trying to turn over there is a smell of gas but nothing leaking. Could really use some help with this thing please

 

I should state that Its AWD

 

I just replaced the crankposition sensor. Tried to start, it wanted to start but nothing. So I tested the spark plugs by grounding them to the chassis and the color is Orange. I test it on cylinder #3. I replaced cylinder #6 coil over due to it blowing out. I'm off tomorrow so ill be pulling all spark plugs and testing spark in all cylinders.
