Car is a 2008 Dodge Charger

So long story short, I had a mechanic work on my car because it has a bad fuel pump. I know it was a bad fuel pump because I tested it and it gave a code. The next day I drove it and it ran out of gas saying I had a quarter tank left.

I’ve ordered a new fuel pump, timing belt, spark plugs, fuel injectors, and fuel pump relay.

If none of those work, what else would be the issue?
