I washed my VN's engine today with a high pressure water spray now it won't start I did also wash the coil pack cause it was caked in crap. I managed to get it to fire but it coughed and spluttered now won't fire at all? I reckon it's the coil pack or the DFI but I haven't checked the spark yet however I did notice the smell of fuel after trying to start it. Is it bad to wash the engine? Has anyone had this problem and how was it fixed.

Check that water has not gottne into the coil pack plug. If possible, get an air compressor and blow dry the entire engine.
