I have a 2012 Chevy Malibu and it will turn over but won't stay started

What is your question?

My car won't stay started more than a sec or two. I was told it was my timing chain and got that fixed. I was told it was a battery and I got that too. It's still doing the same thing and I've had my car in the shop more than I should . I'm furious cause it's not clear what the problem is but it's costing me. Please help me

What makes this problem better or worse?

Nothing
