Audi80B4 does not start..motor jerking

my audi80-avant B4 has been in lukewarm condition for a long time with extreme motor rucksacks. yesterday he suddenly went out on the autobahn and no longer sprang up. the ADAC checked everything at the ignition and everything is ok. because of the ruckeln I have already changed everything and over-examined (new distributor m.finger, ignition cable, candles, gasoline pump, temp.sensor). all are stunned ??? there is probably in the big room münchen and around 80km an audio freak that can help ? would be great.
