My 2000 bmw 328i won't stay running. i crank it up and about 3-4 sec later it shuts off can any give advice
Hi Vlad
This sounds like fuel pump problem, or maybe even a fuel blockage in the filter, as what might be happening is when you trun over the car a small amount of fuel is getting through and then running out quickly and not keeping it running, so either the fuel pump has an intermittent fault and only runs for a short time and stops, or your fuel filter may be blocked and needs replacing, to find out if your fuel pump is ok, turn the key so the lights come on on dash but dont run it, go to the rear of the car and listen to see if you can hear a humming noise, what might be better to do is get someone to be at the back to listen as you turn the key, or get someone to turn the key while you listen, if you hear the pump hum, then that will be ok and then you might have to change the fuel filter. this is what it could be, however there may be other things involved, but that would be a good place to start.
Hope that helps
