Hello. I've got a 97 Boxster tip with 25,000km. The odd thing is it starts perfectly when cold. But when I've driven it and let it sit for a couple of minutes (have lunch, go to the grocery etc.) it has a hard time starting that I have to step on the throttle a few seconds to keep it revving enough for the engine not to stall. It runs fine again after. I've posted this on another forum and they've pointed to the MAF which I doubt (no CELs) or the fuel system (which I thnk is more likely). IT's been going on for a couple of months now and is starting to irritate the heck out of me :cursing: . Can someone please enlighten me on this? Or if anyone has experienced this before? Thanks.

I had an import vehicle a few years back with similar symptoms. Car would start up when engine is cold but would not fire (engine turns) after driving around. Mechanic replaced fuel pump motor, and that solves the "hot start" problem. Turns out to be electric motor on pump was going bad, motor will turn when cold but will not turn when hot. Motor will only get progressively bad until car will eventually not start at all.

My 99 Boxster has over a period of six months been doing the same thing. When there is plenty of gas and the car is cold, it will start right away. I had to get the bendix motor lubed because of excessive cranking. I also replace the fuel relay switch and neither did any good. When the car has been running for ten to fifteen minutes, the car will not fire up, just cranks and then when it does eventually start, there is a strong fuel smell. Do you think it might be the same problem? And did you replace the fuel pump motor? :soapbox:
