Hi all, I have a 2007 2.2 diesel I parked it up last October while I was doing bots and pieces I started it in February and as expected it fired right up however I tried starting it 2 weeks ago but it wouldn't even crank over theres a clicking noise from the glow plug relay but nothing else the starter was tested and is fine, I'm stumped any suggestions would be appreciated, thanks
