The ur-quattro 20V has these.  They're common on the domestic versions
of German cars.

Have you got the fuse slot on top of your fuel pump relay?

If so, recreate the failing situation, switch off the ignition, put a
fuse in the slot, switch the ignition back on, and wait four seconds.

The fuel pump will run.  Let it run for half a minute, and then try
starting the car.  If it's as bad as before, the problem is probably
sensor/electrical and I'd start with the ground wires to the manifold.

If it starts more easily, wait until you can repeat the test - but
this time pull the connector off the warm-up regulator before testing.

If it's bad again (but was easier last time) I'd point the finger at
the warp-up regulator.  If it's easier (and was easier last time)
something, somewhere is leaking fuel pressure back into the tank.
