Post 04 Mustang Trouble Code Help


I am new to this forum and need some assistance. I would like to learn more and more about Ford Mustangs and I hope someone can help. I have a 04 Mustang GT 4.6 2V with a V1 Vortech Procharger on it and I am currently using a Diablo Predator hand held tuner. Ever sense I ran out of gas I throw the trouble code p1235 Fuel Pump Control Out of Range, and at WOT both short fuel trim go to 25 and she spits and sputters, and struggles to go over 5000 rpms, like a lack of fuel. So I went ahead and looked at the live chart and I saw that fuel pressure was at 50.00% and fuel rail pressure jumps down to like 6 psi. And I am stumped. If anyone has some feed back on what to do next step that would be appreciated.
