Default Blow and Dont Go

1998 C5 convertible
the car had a blow n go device in it. The device was removed and now we have no fule pressure. I have power at the plug by the pump. Fuses and relay checks good. I do not hear the pump when the key is turned to the on position. The car had ran flawlessly til the guy took the device out. The area he worked on was the (key) ignition switch.
Is there any wiring down there will tell the car the com not run the pump?
Help Is much appreciated. The blow n go company will pay for the repairs but I know there is something goofy going on cause the car ran with the device installed

So you checked the relay and fuse...have you checked pin 30 to ground with test light hooked to battery positive...relay removed... you might have issue on GROUND SIDE !!...G104 is fuel pump ground...that is what you are checking with test light !!...G401 is back by left rear tire on frame rail !!
