Hi everyone!

I'm a lurker on this board but definitely not new to the Boxster online community. I have a 1998 2.5 with some cold start issues. When I let the car sit for more than 24 hours, I have issues starting up the car. Upon starting the car, the RPM slow drops and can not be maintined above 800 and will slowly drop until the car turns off if I do not restart. The car the lights on the dashboard (odometer) and anything electrical will also start fluctuating going from full brightness to a dimmer brightness. If I give the car a bit of gas, it exaberbates the problem and the car will turn off if the RPM gets too low. It takes around 2-3 starts to have a stable start up without any problems.

The problem only occurs on cold starts when the car has sat for more than a day and will not happen if the car start ups were less than 12 hours apart. No CEL, no hestiations or blips after the car has slightly warmed up. THere is a noticeable, automated rise in rpm to around 1600 within 1 minute to 1 minute 30 seconds of starting the car, and the rpm will stabalize and everything is back to normal. Usually the car doesn't get there and I have to restart.

Is this fuel pump problem, battery problem, or starter?
