I've been having a problem with the 2000 Boxster starting after a fillup. It takes a few cranks and I have to give it some gas, but it usually starts after the third or fourth try. It will sometimes give me a little trouble if I go into a store for a few minutes, but it always happens after a fillup.
I recently had to replace a check valve that was whistling really loud (located behind the passenger side front wheel) but that didn't fix the problem. I have a spare MAF that I'm going to try as soon as I replace the starter (that fritzed this morning), but I don't think it's going to do anything.
Any other ideas as to what would cause this problem? It's driving my wife nuts since she's the one that drives this car to work every day.
TIA!!
