850 fuel pump noises shorty after start

Post by eightfifty2x0 » Thu Jun 25, 2020 1:49 am

Hello! My 850 has got an issue with the fuel pump. I guess it is the fuel pump, because i dont know what else could it be.
Here is a video of the problem.
Notice how a rattling noise is to be heard shorly after start.
The car has no problem when driving, nor when idle and nor when am accelerating.
Could that be a failed fuel pump? or, as an 850 owner i know said to me - a bad relais?
I have been told to check board computer for failures. But this one seems purely mechanical

I can't think of anything else on an 850 back in that area. ave you tried a stethoscope or even putting a screwdriver on the pump and your ear to it also works and see if you can isolate the noise to the pump?

Hi, Neil. No, i solely depended on my hearing. There are two covers over there and this sound comes from the bottom one, which is the pump. And i dont have the tool to remove the fuel pump to see whether there is something wrong with it
