Okay so, this is my first project car and first car that is older (83 datsun 280zx NA) I'm having a weird problem. The car starts and runs fine cold. Can drive it for hours with no problems. Can turn it off after its warm and then instantly turn it back on and it runs no problem. BUT if I turn it off and then come back out after 5-10 minute wait and try to turn it on then the car starts stuttering until the fuel light comes on and then it dies. If I wait long enough for it to cool down then it's turns over and runs perfectly with no problems. I'm not really to sure where to start looking. I read somewhere something about vapor lock which doesn't make sense to me cause it runs just fine without issues. Thought?
