Strange no fuel issue m117 5.6

Strange fuel problem.
No fuel flow out of fuel distributor.

Had an issue with my old one, bought this running used one. Popped it on, engine fires right up and ran, but had a miss on cyl 4. No fuel flow out of the port.

I adjusted the air flow meter as i didnt do it when installing the new distributor. It had 0 free play clearance and was even binding a bit.
Adjusted using the 3mm screw where the allen wrench is to 1mm free play air gap.

Car refuses to start now. No flow on all 8 outputs of the distributor. Jump relay and have to depress the air flow arm about halfway, then all ports shoot fuel out.

I dont know if gauge is accurate but maintains 3bar vehicle off, 5bar when cranking/was running.
