2 door fun 0 Posted March 9, 2010 Hi all. The Yellow peril (1991 G60) has been running fine until not long ago! Went to start her one Sat morning and clunk :shrug: All was quiet. This has now developed in to a clunk that seems to come from the tank..Ie the pump and relay 167 (pump relay) chattering. The clunk happens on key turn 1 when I go to start there is nothing as I turn the key back the relay begins chattering again. I have been reading on Vortex that it can be an Earth problem? The fellas on Vortex said the Earth fails as the ECU controls the pump. So would we be looking for the main Earth of the Battery as a start point of further in to the car?
