Can you get a picture of this switch that you are calling the neutral safety switch? Your vehicle uses a range sensor which does the same thing but is on the side of the transmission and should not be any different between the two engines. I attached the info on this switch.
If you can get a picture of it that will help. However, I am not sure why this switch would cause you to not have power to the fuses. So I am thinking you have an issue on that fuse block. If you have power going into the box but no power coming out then the box would be the issue. However, I am starting to think I am not on the same page as you with what you mean you have no power on the fuses. Are you checking power at the two test pins on the top of the fuse?
