1984 4k - no start

[Bares, Vittorio]

Hmm - could be - etka tells me that is on the fuse block.

I guess the only verification I can do is to pull it, apply 12v+/- to
the terminals (assuming this is typical bosch layout) and see if I have
continuity (and hear a click) between the other 2 ? (I don't have an
extra known working one).

This could be a fuel pump relay issue. Sometimes when they go bad you
will 
lose spark (ignition) when it thinks your revs are too high. The fpr
acts as 
your rev limiter.
