Not yet...
The fuel pump is making noise though...

Yes.

It fires right up again as I'm briefly coasting.

Always at 5500 rpm.

I'm going to swap the coil tomorrow, that's quick and easy enough.

I discovered a bad off idle switch today, $70 new or $30 used, sheesh.
Instead, I installed one of my 16V throttle bodies, w/working switches
and a 16V Scirocco accelerator cable. A little involved, but I saved $30
and now I can sell this large throttle body w/WOT and cruise for $50.
After doing this little conversion, I got very hopeful thinking that was
the problem, until I hit 5500rpm again.
 
Do '84 Sciroccos have a rev limiter, if so where is it located, in the
fuel pump relay?

Thanks Shawn,
