Hi guys,
Not long ago I started a thread about a cold start issue I was having. That thread is here: http://www.alfabb.com/bb/forums/milano-75-1985-1993/563538-milano-aav-tts-spec-questions.html
Turns out it's not so much of a 'cold' start issue, as I found out after several consecutive days of driving the car. When driven days in succession, the car starts right up on the first crank from cold even in 40-degree temps (cold for California!). But when the car sits for a week or so, I'm back to many tries before the car finally fires.
I think what's happening is that the car's fuel supply is draining back to the tank when the car sits. When I go to start it after it's been sitting a week, the fuel pump has to get build pressure all the way back up to the intake plenum before it finally starts.
So, my question is, what component would cause this to happen? Is there some kind of valve that holds pressure in the fuel system when the car is not running?
