Thanks for the replies guys.
BB In CA - I discontinue the start after 6 secs approximately as the engine does not give any indication that it is going to light off. The 6 secs I talk about is after the lever put forward to the Idle gate and you wait and watch T5 and the other gauges for the light off. I suppose I'm still a bit cautious when it comes to hung starts.
Industry Insider - Sir I stand corrected.
Victor Papa - Thanks for an excellent description of the system and how it works. I have re -read my original post and I think I need to clarify it doesn't matter which engine you start first either Number 1 or 2, it's just which ever one is up and running, we get the problem on the other engine. Got me a bit perplexed and I'm sure some my Captains are quietly watching the discussion here lol.
Cheers & Beers
