[urq] More URQ weird behavior

[Martin Pajak]

Ado,

This means that wrong fuel pump relays were used.
The original fuel pump relay should have two large spades, one medium and
one small (in a corner).  The small one is the ground signal from the ECU.
ECU will not trigger the fuel pump unless the engine is cranking.

Please check the relay and let me know if it's the proper one?  

My '83 not only did it have the wrong fuel pump relay, it also had it hard
wired, so it was acting like you said, pump running with ignition on.  
That is one way mechanics "fixed" the 4k RMP and overboost cutouts.

I know that suppose to be, but have done it numerous times on this, and 
other 3 Ur I used to own (all '85, '86 swiss models with MAC 02c). Last 
time last weekend to be exact, when checking CIS pressures.
