Hiya, can anyone tell me where the fuel relay is for my 89 318i (m40) please?. in the fuse box i have relays in K2, K3, K4, K5, K7 and K10, what one of these is the fuel relay. My haynes manual is c**p, should i have a relay for the fuel pumpat all?
Thanks

There's a black plastic cover at the back of the engine bay,you will find the fuel pump relay hiding under there,at the fusebox end.FPR is the one with a green/violet wire(one of 4 wires)going to it.

Many thanks
