The fuel pump on my zs has started buzzing, is this an early sign of fuel pump problems or timing solonoid?

got no warning lights or anything, still drives ok,
Does however misfire sometimes on cold start, not very often tho

Are you sure it is the fuel pump?

The EGR valve commonly buzzes when active and although annoying can be regarded as normal.

timing solenoid on these will give a buzzing but unlike the sdi on msa11 management should shut off when the engines not running even with ignition on

Just because you are paranoid, it doesn't mean everyone isn't actually out to get you :p

Start to worry when it doesn't buzz!

ETV, welcome to the 'everyones out to get me' club. Best cure is not to deny it but to justify it
