What is "AIC"?
Why did you disconnect/plug the EGR?
The fuel supply system is totally independent of the EEC version. It's a completely separate circuit that is not controlled/managed by the EEC other than switching power on/off to the fuel pump relay. Single or twin pumps does not mater as long as there is a fresh supply of pressurized fuel.
What is the fuel pressure doing when the engine stalls out?
