Gen1 B58 HPFP swap no start.

Hey all I'm in the process of trying to swap my gen1 to the TU HPFP. Got everything installed but now the car won't start. I swap back the stock one and it starts right away. I have a custom tune ready to install but I wanted a clean start up before I flashed. Any tips

Sounds like a faulty install or unit to me. The HPFP is a mechanical device controlled by electromagnetic signals. Nothing else would make sense.

The position of the fuel rail wasn't quite right so it wasn't sealing with the pump perfectly it seemed. I had to mess with it a bit to get the connections flush.
