cranking problem
 

i have a 95 Z28 and when the car sits for about a hour it takes it a little while for it to finally start, the only thing i can think of is i put a high flow fuel pump.

does it turn slow? Could be heat soak, or vapor lock (do you have headers?)

Does it start fine after it sits overnight? Or does it only happen when its warmed up-i.e.-startin within an hour or so...

it does it when it sits overnight and after it sits for about an hour, just long enough time to cool off

bump! because i have the same problem!
