What controls the running of the fuel pump ? mine switches on with 2nd position on key and stays on , don't think its supposed to do this , probably wrecked the pump I've just replaced ! Wedge 1e ?

Unplugged AFM , pump did NOT run , does that mean relay is not switching fuel pump off when it should do ?If so which is the fuel pump relay as the book says nothing about it and the relays don't either ?

She's sorted !!!! brilliant. contacts were touching inside black oblong box on AFM BEFORE turning engine over.So bent them apart slightly - not very techy I know - just enough to stop fuel pump coming on too early.No more pumping when only red dash lights on ! Blaine , do you think the nasty backfire will now stop , was AFM to blame ? Put some new spark plus in 2 days ago and that made a dramatic difference to running and seemingly more crackling , popping /noise .
