Odd Starting Problem
2001 Base Boxster. This problem has just recently popped up. In the morning I will go out to start the car and when I turn the key the engine will turn over and attempt to run, but will not fully start up and when I release the key the engine dies. This will happen 6-8 times and then the engine will completely start. After that it starts and runs fine for the rest of the day and then it happens again the next morning. Not sure where to start with trouble shooting this problem. I'm wondering if this might be a result of some check valve failure that allows the gas to drain out of the injector lines over night?
Any suggestions? Thanks!

Maybe carefully listen to the pump -- have the front trunk lid open, and the pump exposed by removing the covers/panels -- when you go to start the car when the starting problem appears.
Then again after you know it will not appear.
What I'm thinking is you'll not hear the pump when there is a starting problem, or it will sound different, erratic, or intermittent compared to what the starting problem does not appear.
There'll be a marked difference. You may have to enlist the help of a friend so you can be right over the fuel pump. Be sure the A/C is off so there is no chance the radiator fans will come on and interfere with your listening to the fuel pump.

Just wanted to do a follow up. More research indicated possible dirty MAF sensor leading to the problem. So last Saturday I replaced the MAF sensor. Old sensor was quite filthy. Also removed and cleaned the throttle body. The intake was coated in a dirt/oil film. Possibly from the after market K&N air filter. Replaced with OEM filter. Also replaced the spark plugs and spark plug tubes. Car is running great!

A spray can of CRC brand MAF sensor cleaner, about $5 at WalMart, does wonders.
