I have a 95' Automatic TDi XS Discovery and it won't start! The battery seems ok cos' the lights are really bright & everything else seems to work ok. The relay assembly clicks and then the fuel injection pump buzzes when the key is at position III but nothing at all happens when you turn once more to start! Has anyone any ideas cos' this is my 1st Landy and i'm not too experienced with motors & electrics either!
