911 SC 1980 running bad after CIS rebuild

Hi everyone,

i need the help of this great forum.

so to me: i own a 1980 911 SC US. I put the engine out and made a complete rebuild of the injection system (new seals everywhere, new fuel lines, fuel filter, spark plugs, valve adjustment) . It should be vakuum leakproof.
Before the rebuild the engine was running smooth idle but it was nececarry to do the rebuild...

ok..
the engine is now in the car tried to start it. So yesterday the engine startet relativly smoothly and died few seconds later

today i tried again. the engine starts but it runs like tractor (not smooth, sounds horible) and dies if i don't move the throttle My first thought was a wrong ignition timing or less fuel...

So what i checked:

I checket all injectors, Fuel is cooming and all injectors spray at same level,
I put cylinder one to tdc, then the rotor points exacly to the marking of cylinder one (i also market the position of the distributor bevor removing, fits perfect)
i checket the position of all ignition wires to the firing order, fits

so ok. I ordered a CIS Manometer to check the system pressure

Any ideas ot tips what it could be (i read a lot in the forum but i'm not getting into the problem)? i'm really confused and a bit down...

Sorry for my bad english.
Best regards and thanks. Philipp
