I have a 95 chevy caprice with 5.7. Just recent I have come on this problem. when I try to start up it will not, but after a few turns it will. when it starts up it sounds as if it's not getting any gas when it first starts up. Then you can hear the motor turn up as the gas flows. This happens some times. I drive the car after that and it's fine. Could some one please help with this problem?
