I'm trying to get a new 170 that I added CDI run in.

First run, 30%CP, 17-12, 2 turns out and 3K...normal rich run.

Second run pretty similar but started surging half way through the tank so I stopped it and richened the punp 1/2 turn. Re-started and it ran very well.

Third tank started very well, consistent run until 1/3 through the tank and then it quit without warning (no bang or surging just stopped) and would not re-start. I noticed that there was no fuel in the line up to the injector although there was fuel up to the pump. Even if I open the throttle to full and turn the prop over by hand no fuel seemed to be getting to injector.

Now...this was the first 170 I added CDI to, could I have screwed something up? What should I check first?

Colin.
