Look for two small black boxes mounted on the firewall on the passenger side. They are up high and are side by side. It should be one of these. On my 1995 they are both identical. You can switch the wires around on the two boxes and this will test if one of the relays is bad. Another good test when trouble shooting a fuel pump is to find the wire going to the pump and check to see if power is getting to it when you turn on the ignition. Use a basic 12 volt tester and have someone turn the key on. I just went through the same thing with my 1995 Astro. Mine turned out to be the pump, had to drop the tank and enjoy a day crawling around in the dirt.
