oldhoo07s
I am experiencing similar symptoms as MarknearChicago in my 2007S Boxster with 36K miles. Always starts fine when cold. But when road temperature hot and after being off for 5 to 10 minutes the engine will crank, will fire what seems to be once or twice but then cuts off. After 3 or 4 attempts like this the engine starts up and runs fine with no issues. Could this be a crank position sensor problem? Are there two of these sensors, which is implied on Pelican Parts, one on each side of the engine. And if so, where are they located? On Pelican Parts the Bosch (OEM) sensor is $30.00 while the Porsche part is $200.00 plus so if DIY big savings on parts alone as opposed to dealer fix. Any suggestions/info will be greatly appreciated.

Marc, thanks for your input. There is no CEL. I have not checked for error codes - I will check this weekend when I will have opportunity to do so, I have a Durameteric (not pro). I will also check the sensor to see if there are any loose connections. But I ask that anyone who can, please add to my limited knowledge as how to best access the sensor with no lift - passenger side, remove rear wheel, straight in at approx. 2 o'clock, on side of engine. Thanks in advance.

Hi,
Nope the car doesn’t start at all. It just cranks then dies. Im having the car towed to the shop but the weather is not cooperating. Its been raining here. Intertropical convergence zone thing that’s bringing in all the rain. Dont know if its the relays, the crank sensor or fuel pump... hopefully the mechanic can diagnose it☹️

Hi,
Yup the car just cranks. Like it doesn’t push thru to starting the car. And yup the tach needle moves just a tadh needle moves just a little towards the end of the cranking just before it stops. I don’t know how better to describe it. Having the car towed this week. Crossing my fingers that its not the fuel pump or anything expensive to replace☹️ Will update. Thanks guys.

You said "fuel pump is not unusual" then "failure rate is not high". Those seem to be contradictory.
In any case, buying a fuel pump in case that's the problem is a waste of money because your latter statement is true and hence by definition it's a bad bet.
You don't have to try everything that could be the problem. In this case it could be the immobilizer (much more common problem) or just the fuse on the immobilizer. It could be one of the relays. It could be the ignition switch. It could be the crank position sensor. And it could be a dozen other things. Diagnosis is the best way to track these things down, starting with the common problems and the ones easy to test.
