I had a little extra time this morning before heading out, so here is your test! and let me know what you find. PLEASE follow each step carefully, and accurately!
OK, here is your fuel pump relay
and here is your fuel pump fuse, Connect the test light or meter to a ground source, and then the other end to the metal part at the top of the fuse (key must be in "run" position)
After taking the relay out, Connect a test light (OR a meter) to a 12v+ source (the bolt right above the fuse box works well), and connect the other side to this tab.. This will confirm you have a ground source to the relay.
now we will check to make sure the PCM is sending the relay the "on" signal. Connect a test light or meter to a ground source, and the other to this tab. now have someone turn the key from "off" to the "run" position. The light should illuminate for 2 seconds and shut off (or meter will register voltage, and then show none)
IF all of those test are looking good, then we need to go to the final step, checking the fuel pump feed wire. Using a jumper (like a paper clip) insert it into both of these tabs, this will provide power from the 15 amp fuel pump fuse, to the gray wire. Now go back and test the gray wire. if it shows very little, or NO voltage then you need to run a new wire from under the hood to the fuel pump. PLEASE be sure to also test the gray wire at the connector in the trunk. If by chance water got into that connector, or somehow the wire between the connector and the pump got water into it, it would be corroded and offer a very poor transfer of electricity.
