Starting Problems....

[Dext986]

Hello all. My 2000 Boxster, runs like a dream, but has just one little problem... She starts first time every time...without fail. But..... If my first journey of the day only lasts about 15 minutes, and I go to restart it again after 10-30 minutes, she won't fire up. She will turn ok, but its like petrol is just not getting there. then after about 30 minutes, she fires up and great for the rest of the day. If the journey is more than 30 minutes, I can stop and start it no problem. It only happens if the first journey is a short one..... Any ideas??? I changed the breather valve on the filler nozzle.....someone mentioned something to do with the choke might be sticking? Any ideas appreciated before i take it to a dealer to look at and have to sell a kidney or something.... Thanks

If you use the search function "crank position sensor " or "cps", that may throw up an alternative, though the cps usually fails when hot every time you try to start the car, not just for the first run of the day.
So there could be another problem lurking too.....

I have hooked it up to a reader and it says nothing, no codes found....
Would any of the sensors cause a code to be generated?

Do I bite the bullet and take it to Porsche Dealer??
