Hi, we have just purchase a golf mk3 gti 8v 1995, been running fine, yesterday went through a puddle, car cut out, wouldnt start, called RAC, it started again, went round corner to check it, the dizzy cap centre contact was missing and just spring. Today we have replaced the dizzy cap, but is now not starting!

Doesnt seem to be any spark at plugs, also tried plug on coil cable and no spark, any suggestions?
Many thanks
