Needs gas at start up

That could also be the culprit possibly, but usually if it's the idle control valve it would die when coming to a stop. He didn't mention it dying at idle, but it would still be a good idea to check it out.

Fuel pump maybe??

I have never experienced this on my Porsche, however I had a Holden ( think Australian Chevrolet) V8 that suffered similar problems on 2 occasions. The starting got progressively worse until it would not start at all.

The way I used to start it was by opening the air intake tube after the box and filter, then pouring a small amount of fuel in the air intake. Worked like a charm, until I got around to changing the fuel pump.

I emailed Pedro (http://www.pedrosgarage.com) and thought I'd share his solution in case anyone else has had this problem.

"The Boxster does not like the accelerator depressed before or during start up.
If the accelerator is depressed, the throttle positioning sensor tells the DME that the throttle is depressed and it automatically goes into safe mode, cutting back on the injectors and retarding the timing. That's why it takes so long to start.
Just depress the clutch (or brake if Tiptronic) and start it up without depressing the accelerator at all."

Out of the dozens of mechanics I contacted, Pedro was the only one who knew I was unintentionally putting the boxster in safe mode, thus requiring more gas at start up and sometimes causing the car never to catch.

No more start up issues!
