When I put vacuum on the FPR the pressure drops to to as low as 42psi. No hose connected it stays at 50psi as it is when the hose is connected
Fix your vacuum to the FPR.

Hi Bill you are correct. There is 0 vacuum coming out of the intake. The tube on the backside of the resonator leads to an air system with a pump and diverter pump. Do you think that could be a cause? Although I would think those would trip a MIL

No, I don't think that larger (1-1/4" OD?) hose on the back side has anything to do with the FPR vacuum.

You have to take that plastic plenum off and start looking inside of it. Even if the two halves don't separate, the two big holes connecting to the air filter and TB should give you plenty of access.
