You would need to determine if power is getting back to the fuel pump at the connector or power line. I think is is a grey wire. May be a ground your missing. I assume you replaced the relay.
Invest in a multi-meter.
Test the fuel pump pin on computer.
Pin 1 24pin black connector = Fuel Pump Relay. Look on Page 4 on this web page, url below copy & paste it to new browser window.
