2001 Blazer with no fuel

I have a 2001 Blazer that just stalled out. There is no hum from the fuel pump (thinking its that). Tried to test the red wire to the relay and there was no hum. There was also no spark from the positive when I touched the wire. Not sure if there is something else to use to test the pump. It he 114000 miles on the thing and it had no simptioms of failing it just stopped and it gets no gas. It will fire up when there is gas poured in. I would also like to know if there is a diagram for the fuse box to show the relay. I tried alldata and they do not have the info I need and I know Chiltons does not have it either. Any help would be greatly apriciated. If I can avoid buying a fuel pump I will be very happy.

I know this would be a pain, but I would just check all the fuses. If you have the factory user guide it should have the diagram in there. Also call a Chevy dealer and talk to someone in the service department. Good Luck.

The "no buzz" is the pump not priming I belive. Same thing happened to me, and I had to have the pump changed.
