[s-cars] Engine cut-out - still

[Robert Myers]

Yes, the fuel pressure has been checked.  In fact, that's how the 
second bad fuel pump was discovered.  The present FP is good.  The 
FPR is brand new.  The MAF has been swapped between my two RS2ed 
urS6es with no difference.  The FP wiring has been recently modified 
so that power to the FP is relayed directly from the 
battery.  Measured voltage at the FP is excellent.

Good suggestions all but I BTDT.
