Whipple equipped 5.7 Denali wont start with fresh engine

I am stumped on what to do with this thing. Fresh long block and it wont pump fuel due to a 14 trouble code coming up on the whipple check engine light. Dual ECMs interfaced- dealer install on the supercharger with 111.000 miles on vehicle. Cleared oem unit with no effect. PLEASE HELP!!!

Does fuel pump run when you first turn key on?
