Thanks secretagent214, I'll double check the relay and and pump connections, howevert, the frustrating part is the car will start fine right now, so I'm sure all will test ok. I have never had the car disabled for more than an hour or so, and generally not in the driveway when I could check the above suggestions.
I have been having the exact same problem w/ my '99, the only exception is last Friday, the engine died at 65mph. To recap, on 7/23 after driving ~25 miles home, I went to run an errand, starter cranked as usual, but engine wouldn't turn over. I let it sit about an hour, started right up and ran fine, next day, similar experience, 25 mi drive, no start, hour sit, started and drove 250 miles that day with many stops & starts. I replaced the 11 year old ignition switch and it continued to start for a few days, then once again left me stranded. I used a P-code reader... nada, but after sitting, she started right up. I have put ~1,000 miles on since this first occurred. 1999 Boxster w/96k miles. Fast forward to Friday; driving to work ~65mph, felt a hiccup, saw the dash warning lights come on for a split second, put the car in neutral and all was fine, the car continued running (again, no codes). On the way home, same thing, however the engine quite completely. AAA towed the car to my house and after unloading, the little SOB fired right up!!! Can somebody post the Crankshaft Position Sensor part # for a 1999 Boxster?
You may want to check if it's coming from the door latch. Wrap some electrical tape around the loop and see if the problem goes away. If it does, look to see where the tape is getting worn (top or bottom) and adjust the position of loop and see if that eliminates the problem. This is a good first step as it doesn't require any door surgery.
Here's on manufacturer that I've seen on-line. No personal experience though. Anzianos
I installed the K&N replacement filter about 3000 miles ago. So far no CEL or other issues - '99 Boxster -62 k miles. It had run the OEM filters until now. I guess I'll keep my fingers crossed.
BoxsterBob replied to way2fast's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Go here: http://www.autohausaz.com/search/product.a...20Mass%20Sensor That's where I bought mine, at the time it was the best price I could find.
BoxsterBob replied to way2fast's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)My '99 Boxster experienced the exact same conditions, hesitation at ~5500 rpm and same CEL codes. I cleaned the MAF and it got better, but codes returned. I eventually replaced the MAF and all is well, no more hesitation, no more codes. Good luck!
