You just had a valve job done on your 2002 kia optima drove it home fine and now car wont turn over wants to start by wont stay running any idea what it is Fuel pump was replaced as well?

Call the person who repaired the car and tell them what is going on. But what you write above makes no sense. You say, "(wont turn over) (wants to start) by (wont stay running)" If it won't turn over, how does it want to start, and how can it be running in the first place? Did they replace the fuel filter. If not, they should have.
