Crank but no starts

What is your question?

My car will turn over but won’t fully start been told it’s the fuel pump I changed it and that didn’t work. Changed the crank sensor and that didn’t. It’s a crank but no starts. Cranks at a consistent pace and when it try’s to bark off it backfires when giving gas nothing happens. I have no clue at this point.

How long has your 2010 Dodge Charger had this problem?

A week
