Hey Zoran:
        I had a similar problem that baffled me for weeks. I asked my favorite
old-timer VW mechanic about it, and he said "run a ground wire from the
distributor to the case." I ignored his overly simple solution, and
tried a new fuel pump, ECU, relays, Hall sending unit, etc. After all,
the distributor body was METAL mounted in a METAL engine case - it
couldn't be any more grounded. After nothing I did seemed to make any
difference, I finally made a little pigtail to run from the distributor
to the engine case, and it started right up, and has run fine ever
since. Go figure... Neal
