Fuel system priming/purging

Hi,

Is there a particular set of purging steps that should be followed after having the fuel system (on the kv6) apart? I had the fuel rails off and injectors out to be cleaned when doing the thermostat. I simply plugged it all back together again and assumed the air in the fuel lines would be pushed out. But with the poor starting could there be air trapped in the fuel lines somehow which starves the engine for the first few seconds while cranking and firing up?

Cheers!
