Title: Electrics gone haywire?
Post by: sushi on 21 June 2010, 22:10

I'm sure when I unlock my car then when I open the drivers door I hear the fuel pump prime  :huh: sounds exactly the same.

anyone had this before ?

A little while back the car locked itself with my key in the ignition ( not turned on )  and somebody said check the door because if it is opened it shouldnt lock itself but the interior light comes on when I open the door as does the paddle light. 


If i close the door and open it again the fuel pump doesn't prime again.  More annoying than anything at the moment.

Any tips appreceiated I am useless with electrics.

Mk4 Golf Gti btw

I would think that is not normal, the fuel pump should prime when you put the key in.

Apparantly to aid with cold starting?

Oh  it does prime when I turn the key as well which is why I was sure it was the pump priming.

I have heard of this before,   Seems like a waste of motor running time if you ask me, im sure they have their reasons for it though.

Well at least I'm not the only one who found it a little odd  :laugh:

im guessing its for something else on the fuel pump relay circuit, rather than the pump itself.
