2008 Kia Optima - Ran out of gas - now this

2008 kia optima. ran out of gas.put gas in it, wont start. pulled gas pump, it is fine. emptied gas tank and put in new. car has spark, fuel, took off boot and sprayed starting fluid, nothing. changed spark plus, nothing. help

Is it possible the timing belt broke, and that’s what caused the engine to stall the first time?
