I should have mentioned my car is a '69 280sl. I have tried waiting for the fuel pump, that's not the issue. Like I said, starts instantly after it's been run, even like 1 to 2 hours later, but when cold, I crank it three times before she fires up. The car has electronic ignition which my local benz expert tells me is a good modification.
I'll try a search on the subject but if the CSV is not the next likely culprit what is?
