No I have not, but I did double check everything twice in the mechanical fuel system. Im going to start looking into the electornic part more. Im gona check the rezistor box, ecu, voltage through out the sys.

11.7 V sounds a little low... maybe check your pump wires and or grounds?

the car was not running, just the ign. was on and the car had been sitting without running for about a week. So I think that was ok for voltage cosidering that the car had not been starterd in a week.

once I saw guy having his FPR attached where fuel gets int the rail, so when he was increasing fuel presure (squizing fuel hoze) actually he was restricting fuel geting into the rail, stupid thing, but here when you are "increasing fuel pressure" there is less fuel/fuel presure on injectors. Could post some pics? This will help I believe.
