The PCM is what tells the relay when to send power to the fuel pump. Have you checked for poor terminal connection between the fuel pump relay control circuit and the PCM? Also, using a test light connected to ground, check to see if you are getting power to the ignition feed circuit at the relay. If you are, recheck the contacts to the relay.
Let me know what you find.
