Can anyone help with a starting problem I have with my 2003 plate, 4200 GT? I foolishly left it in the garage without starting for about two months and the battery went flat. It is a new ( less than 6 month old battery) which I have charged. When I turn the ignition key there is a clicking of relays that sound as if they are racing each other, and the lights in the dashboard pulse on and off in time with the relays. The car won't start. It behaves in the same way when I also try attaching jump leads from another vehicle. Any suggestions on where to begin checking please?
