Ok so I eliminated the primer pump and put another unit on. This one does not make air bubbles when pumping and it is a much more “firm” feel when pumping it.
I also noticed I had done something kind of dumb. I accidentally had the fuel return banjo bolt in the fuel supply location. This banjo fitting has a check valve in it. I suspect this would limit fuel going into the pump in the supply location. I switched that all around and bled the system again. To my surprise the motor started and idled. It idled really rough at first but began to smooth out. As it started to smooth out the turbo whistled some and then it fell on its face again. After that I was unable to get the motor started again regardless of what steps I took.
I really am at a loss with this pump. All lines are now 100% correct with brand new copper washers. The hand pump is in good shape. I am just not understanding why I cannot get this thing to run properly.
