Gen 5 Camaro Tuning, Diagnostics, Dyno results - Fuel Computer HELP!

I finally got my camaro back from the body shop last week. We then quickly went to work installing a fuel system from Vengeance Racing. It comes with a 4gal surge tank with twin bosch 044's and a return line. Now the issue seems to be that since the stock pump is pushing fuel into the surge tank the stock fuel pressure sensor is not getting an adequate reading to continue running the fuel pump. and if the stock fuel pump doesn't pump neither do the bosch's. Now I'm not a fuel system expert, so any and all thoughts are appreciated. And yes I will be calling Vengeance in the morning to see their thoughts, since they assured me all would work fine.

Not sure how you have it set up but if anything put some fuel in the other tank with a gas can to get it running and you should good to go. post pictures
