Basically I’ve had issues after issues with my broken down smax, still won’t run after four new injectors with new seals, a new map sensor, fuel filter replaced, a brand new leaks off pipe kit and sensor, I’m about to try replace my fuel pump as I seem to remember it making a buzzing noise when I turned the key which it no longer does? Should it make this noise?

I can get the car to run with a spray of easy start but it feels sluggish, smokes heavily and dies as soon as I let go of the throttle! It won’t idle at all?

any suggestions please?

I think the first thing would be to run some diagnostics and see what gets thrown up. Get a decent adapter and Forscan. 
It could be many things. Sounding like fuel issues with it not starting without easy start. 
pull the leak off pipes and see if anything is coming out. 
Fuel pump is a big job so hope it isn’t that. I don’t think your model has an electric lift pump so shouldn’t make any noise when you turn the key.
