I have a Golf s '99 that won't start. It fires up for a second then dies?

If I pump the accelerator I get a rev but the engine still stops.
The dash doesn't seem to be working as the dials do not move. also the clock (digital) appears with a few lines on it and the mileometer is the same. tHe battery gives of a quiet whine also
The sun roof has been leaking recently and the car is getting a bit damp inside . do you think it could be the fuses? i've looked but they appear ok to me
