Help PLZ M3 Fuel prblm!

Mayn I need some help. Well I have a 95 M3. Jst recently It started stalling right after it starts. It chokes real bad like its not getting fuel, then just dies. I can rev it up but it really sounds bad and acts like its not getting fuel, then basically dies. It was never this bad but during the last few weeks its would suddenly cut off completly while driving and just as suddenly be back to normal?? Know wont start. I dont know if its a bad fuel pump or filter of maybe an airflow problem. Any help would be awesome. Avus blu -95

fuel pump

I don't know much. but underneath your spair tire is a plastic cover. underneath it is your fuel pump or what i believe to be a fuel pump. Try there.

Well I would say fuel pump/fuel filter, as for you might think its airflow, when did you last change the the air filter.

The air filter is new and I just changed the spark plugs. I think it is most likely the pump and or fuel filter. Im takin it t the shop 2morrow so I should find out then.

Alright.....

So I had the fuel pressure regulator changed but. My car ran perfect. It started up fine and ran strong for about 3 days. Now its starting to bog down a bit like theres something cloging the fuel... again.. but not as bad. Im thinking i need the fuel filter changed.

Change the fuel filter and run some injector cleaner through... seems like I've recommended fuel injector cleaner 3 or so times in the last week... Any way I recommend 44k, get the kind that goes in your tank. If the filter was bad you could have some gunk in your injectors by now. Plus it never really hurts to use it.

i had this same problem before too. a month of my e36 m3 not running, i trouble shoot everything possible to the fuel system that i could think of, injectors, fuel filter, fuel lines, fuel pumps. i took my e36 m3 to the shop and it was something to do with the fuel sensor thing, i forgot what it was called, something i did even think of, but after they fixed it, the car worked fine. maybe thats one thing to check out, hopefully this helps.
