Auto Electrician Job - Observatory, WC, 7925

I've had a short to ground which made my VW POLO 9N misfire. I tried to see if I could find it and now the car won't start, the Fuel pump won't turn on, power steering light is on and fuel gauge is wonky. I urgently need diagnostics to find this problem. I can't bring the car to you. I stay in Arnold Street Observatory Cape Town. Thank you.
