Hi guys. i've got a 90 mk4 xr3i e.f.i and the fuel pump has stopped pressurizing the system on ignition. you can't hear the loud noise it makes anymore. i've got a feeling it's one of the relays. does anyone know where the relay is for the fuel pump and what colour it is??? i think there's two. one of them is under the dash, it's grey and is still clicking when you turn on the ignition so i figure its ok but as for the other one?????????
