2008 Speedster Supercharged No Start

[retro]

Have a 2008 Speedster trying to figure out whats going on. It will not start or crank. When putting key on dess post it will wake up display but no beeps or no fuel pump run like it should. I even tried putting a key not programmed to it and it will wake up display but no beeps. Buzzer works fine. I am in process of checking wiring. All fuses check out good. I have hooked up sbt scanner tool and it will connect to ski but wont show any data from ecu very weird. If anybody has any ideas on what to check I appreciate it.

The ground for the power panel comes from the DESS post. Find ground side on main power panel. Try jumping it straight to ground and see if it will start and run. If it does then you will need a new DESS post.
