Chevrolet Repair: need colors of wires or diagram for fuel system for 97 chevy g 1500 van, fuel pump relay, fuel pump

Question
I have replaced fuel pump, relay and my van still is not running.  I am only getting 1 volt when checking.  I am puzzled.  It seems as though there could be a short.  Can you suggest anything?

Answer
Hi Brenda...check the pump itself...depending on what year you van is there is a fuel pump bypass wire . put power to it and see if pump runs... if not check harness at the pump for power... if you have power there for three seconds and pump don't run replace the pump...short could be in the pump... hope this helps
