Electrical Problem

[Ronin]

I tried to start the car today but all though it will fire and run for a few seconds it won't run. I don't think that the fuel pump is priming plus I have no electrics to the dash, stereo or lights of any kind but the wipers and windows work. I am thinks there's a bad earth somewhere or something has anyone had the same trouble or similar? If so what was it?
Any help appreciated.
