Default Need fuel pump testing help. 02 blazer

My fuel pump stopped running today so i put a new one in,but it still doesn't run.
Can anybody tell me the right way to check the relay under the hood and the location of the fuel pump fuse? I swapped the relay with the identical horn relay and that didn't help.
I also need to know how to test the wiring at the pump since I can't find a diagram. I do know the gray wire is hot for 2 seconds when the key is turned on.

So far by searching the internet i need to check that stuff,grounds and the oil pressure sending unit also.
