I have a strange issue with my z28, i usually have to try and start my
car twice before it starts, and it always starts on the second try. but
i found a way around it, i have to turn my ignition to A/C and off
again then try to crank it up and it always start that way, my guess is
something electrical or something with my fuel but when the car is on
there is no sign of fuel pump failure any idea what's causing this?
