Frankly it was a bit of a leap of faith... I described the symptoms in detail to a couple of local German car mechanics. Both of them indicated that it could be a sensor issue. Because the car ran perfectly once it did start. There were no drivability problems whatsoever. But the Crankshaft sensor in particular needs to get a reading on the position of the crankshaft or else the computer that control things will not know what position the engine is in and so it cannot make a judment as to when to produce a spark and/or fuel or what have you. But once the engine starts, it relies on other readings perhaps? I don't know... Looking at the old crankshaft sensor, there were no visual clues indicating that it was worn out or damaged. Just a bit of black soot on it. But not much really... I also posted the question online in many different Porsche and Boxster forums and there were some posts from people indicating that the Crankshaft sensor might be at fault. There are also two camshaft sensors but a mechanic mentioned that they were a less likely culpret. And there were two of them, so more expensive! ultimately when i found the $70 price at Advance Auto parts I decided that was a price i was willing to take a gamble on. I did not have a check engine light. And none of my OBD scanners found any codes. And i was not going to invest in the right scanner that finds all of the available codes for a boxster. I almost was going to bring it to the dealer or to a good mechanic and pay whatever fee to get it plugged in and tested. But for $70 and my gut feeling that the crankshaft sensor was a likely culpret, I went ahead and bought it. And it worked! More often when i have taken such a gamble I end up being wrong and just wast money. But the Porsche God's shone upon me this time! thanks
