I have a e50 princeton. I can start the unit then it chugs then finally dies. I get no power to the fuel pump, if I bypass it and power it directly it starts and runs fine. The problem is I can't find a fuse box or inline fuse on this certain model. It has a battery shutoff, large wire for the starter and smaller for ign. There is a 15 amp fuse for that and jts fine. It does power a white control box that the fuel pump wiring comes out of along with other control wiring. Does anyone have a wiring diagram for this model? I don't want to replace this control box unless it is necessary, its just under $2000.
