Ok here's my setup right now: Holley 600 w/e-choke, MSD vac ad distributor, no computer. Recently, I have had problems starting the car in the morning. The weird thing is, it seemed to start better in the cold weather. Is it possible that temperature change could effect the choke settings. I give the car 2 pumps of gas before starting it. The choke closes and everything. But when teh engine cranks over, the car dies right out. I give it 2 more pumps of gas and it starts up w/o a problem. What is causing this?

 

sounds like your lean dude.the colder it is outside the more fuel it takes to run your f body.id check fuel filter fuel pressure (should be at least 6 psi) and the pump itselfe.how does it run after it warms up and during normal driving.i bet the hotter the better.take a few plugs out and see what color the tips are.if they are white your lean black rich a nice shade of grey is what you want.
