When I turn the key on in my car, it will prime the pump (Which seems to take a while, 3-5 sec.) the relay will click under the dash and the car will start just fine. If I just jump in and turn the key to start, the car will sputter and sometimes stall for the first 10 seconds or so. Any idea if this is a fuel pump issue? The car has 63k on it and as far as I know, the fuel pump is original and the fuel filter has never been replaced. I'm just wondering what could be causing that. It seems to run fine when its running.
