W220 S500
Start but no run

Hi there I wonder if anybody could possibly help me I'm sitting with the S500 Mercedes Benz w 220 the problem I have is that the vehicle starts briefly and then dies I have replaced the fuel pump and fuel pressure still seems to be a little bit low however if I choke vehicle completely it will idle indefinitely however as soon as I give it some air the vehicle dies which tells me that there is no fuel going into the system I've checked injectors is power on the injectors but I still don't have a run on a vehicle can anybody please help me
