1999 Chevy Astro 6 cyl All Wheel Drive Automatic

I have a 99 Chevy Astro, last week it took 3 times to get it started(motor turned but no start), then it happened again a few hours later, luckly I made it back home, next day it would'nt start, same crank but no start, I replaces the fuel filter and fuel pump, after this it started ok, but abought 1 hr later, it would not start again, so I pulled the fuel pump back out and replaced it with another new one, now im back to square one, motor turns but no pump, I shortd the pump relay and canot hear the pump, PLEASE HELP.

Check ECM B 20amp fuse if okay-If relay don't energize when key is in run for 2 secs-You have a problem with the computer fuel pump relay control circuit-Relay energizes check for power on the gray wire on the fuel pump connector.
