I was talking to guy here who drives a VW, he says that in his
manual it says that if the fuel pump fails it causes an over
rich condition(in bose systems). Could this be so???

The pump hardly makes any noise now, when I try to start the car,
which is a bit difficult to hear over the racket of the starter motor.
So I checked the wire, which produced 11.5v when you try to start,
also the pump vibrates a little (as if its working).

Fine, I'll check this. Where is it?
