99 boxster leaving me stranded

[tthomas]

Hello Ladies and Gentlemen

I just bought a 99 Boxster with 82,000 miles on it (Manual)

Sometimes after I have been out driving I park my car and when I get back in it it will not crank. I do hear the solenoid at the starter kick when I turn the key but no luck. The engine will not turn. Then the next several hours I go and turn the key and "Holy Moley" it starts right up and will continue to start for several days then it will just die again. So far have changed battery and starter and checked all ground and positive wires and all good .

 

HELP ME PLEASE!

Don't know if this is your problem but had a similar problem with a 2011 Boxster and it tuned out to be the clutch safety switch. Sometimes I could start and sometime I couldn't. There is a lot of threads on the internet about this problem for the 2009 Boxster.

I would also take a look at the crank position sensor, which is famous for failing hot on the Boxster.  When the CPS goes out, the DME thinks the engine is not turning and won't let the car fire.

Since you said the engine does not turn and you've already replaced the starter, I would jump the clutch switch next time it happens. If that doesn't work, I would replace the starter relay. Another possibilty is your ignition switch but it you can hear clicking when you turn the key to the crank that's probably not it. There are systematic ways to trouble shoot this with a multimeter but those two are easy to do anyway.
