Please help. I bought this vehicle which has been standing without a battery for about 6 months. Fitted a battery yesterday and when opening the driver door, the instrument panel turned on, and you can hear the pump running. Inserted the key and then - nothing. It won't turn on the ignition. Even the windows, radio, etc won't work. As you press the window button, for instance, it only makes a clicking sound. The vehicle is still without a radiator as I still need to replace it, but surely this cant cause the ignition not turning on?
