Is it time for new fuel pump on 95 Q45 156k

Hi,

Happy holidays and Merry Xmas

When I start the car in the morning (winter in canada). I hear a buzzing noise for about a minute and after that it fades away. Is it time to change the fuel pump or should I wait for some time?Regards,Wasim.

No, don't wait. A failing fuel pump overheats and then fries the pump controller (FPCU) which costs more than the pump. No sense in having to replace two things at twice the cost. 156K is appropriate for a fuel pump replacement.

Fuel system service history, please.

I agree. Both fuel pumps have been replaced on my Q's. One at about 80K (California crappy gas), and the other at about 160K (almost waited too long).

I'm on my 3rd pump and 2nd controller, shucks its been 60k since the last replacement better budget for another now [in 2006] at 302,000 miles currently.

Fuel pump has never been changed. I dont know if they service fuel system in regular maintainence. I had 60k , 90k and 120k service done on the car. Also replaced the head gaskets about 10k ago.

You're due.

Regular maintenance is minimal maintenance. It is not sufficient for long term care as verified by the previous posts on this baord, especially Q45tech's posts. Read them or be doomed.

you replaced the head gaskets or valve cover gaskets???????

Anyway, id go ahead and buy a new pump, have it at the ready and then replace once it starts getting worse...

Valve cover gaskets.
