As a electric/electronic guy, that chases electrical problems, I suggest you measure the voltage at the pump. There may be some logic somewhere that will not let the injectors fire without proper pressure. IF the pump has voltage, this is a pump problem or stoppage etc. If it does not ... get the schematics and go backwards looking for where it does stop. If there is a common point for supply for both the injectors ... that is suspect! If you have a friend who has the same setup, you can compare results. Happy Hunting
