  1. Airhound, The answer to your question " was it the wire/pin crimp connection, or the pin connector seating? Or…how do you think whatever it was with that pin it came about?" A little surprisingly, once we found the pin and wire circuit with the continuity issue, the wire/pin crimp connection was fine. The problem was in the female side of the connector. We had to slightly squeeze the female connector so it was a slightly tighter fit with the male prong. Why this happened after 7+ years I am not able to answer. As you would expect, the secondary pump is powered by it's own separate circuit breaker and wiring.
  2. Last fall at 970 hours on my 2013 CTLS iS (I purchased new in spring of 2014) the engine died suddenly in flight. I immediately engaged the secondary pump and the engine instantly came back to full power. I ran it a couple minutes on the secondary pump and then tried turning that pump off and engine immediately started to die. Obviously it seemed wise to be finding a place to land, and fortunately we were only 20 minutes from my home base (3OH0), and I elected to continue there on the secondary pump. After hours and hours of troubleshooting we finally discovered a faulty pin connection on the bottom bundle of wires going into the computer module (red arrow in photo below). With a little adjustment to the pin and a small application of dielectric grease the primary pump has run faultless now for 20 hours. My standard procedure is to run both pumps on takeoff until around 800 ft AGL and then disengage secondary pump, and then reengage secondary pump when around 800 ft AGL when in landing pattern.
  3. Andy, When my 2013 CTLSi was fairly new I experienced the exact same issue. Replacing the fine filter on the engine side of the firewall and cleaning the gascolator screen resolved the problem.
