wierd misfire

recently i've been having trouble with my 1991 325i touring.

about a minute after starting, it will cut out (even when under load) and pretty much refuse to restart. it will however usually restart if left a fair while.

i've noticed there's no 'whirr' from the fuel pump that i can hear when turning the ignition on, should i be able to hear the pump priming?

is it maybe something to do with a cold start system?

cheers in advance!

could it also be a crack in the air intake bellow (after the AFM)? This would cause it to stall.. Maybe other vacuum leaks. as well

cheers

it looks like all of the above!!!

i know of a dodgy air hose (small one that goes onto the icv) so i'll sort that.

should the fuel pump make a whirr though? it's silent at the moment.

when they are on the way they "whirr" all the time for while before they go

yeah, the worrying thing is that on most other fuel pumps i've had (inc the one on my old 320i) you can hear a short whirr when you turn on the ignition, this one does not.

coud be deaded?
