Fuel injection guru's...a couple ?'s Options

[biosurfer1]

I tried asking this in another thread but it was an OT question there and didnt get much advice, so I thought I'd try here...

anyways, I was wondering wha part and how does the stock FI hold pressure in the fuel lines when the car is sitting so there is fuel immediatly when started?

I recently fixed my AAR and its working good now and hoped it would solve this other problem but no luck. It seems when the car is cold and has been sitting a while, it takes several cranks to get it going, like these isnt enough gas getting to the engine. After the 3-4th try the car starts and run normally, with the AAR open and slowly closes(as it should). I had a very similar problem in my 911 and there was a part (warm up regulator) that served this prupose and had the same symptoms with it wasnt working correctly. Does the 914 have a part like this, does the fuel pressure regulator handle this aspect? Something else maybe? I was told to check the CHT sensor and have one of those coming, but i cant see it doing much since the problem is right when the car starts and it wouldnt have much time to effect the system, or am I wrong?

any help or direction would be great...thanks!
