All,

I have Wren 75 with a Xicoy FADEC AU-107K ECU. Up until this year everything has been working great. This year though I have not been able to get my turbine to start. From what I can tell the fuel pump is not running during the start process. The system starts, the starter begins but the ignition fails error message pops up on the display. The glow is hot. BTW, its a auto kero start.

I pulled the lines and no fuel is flowing. If I manually tested the fuel pump using my data display interface and it runs fine. I reversed the solenoids to and both seen to be working well. My my position of ignorance I have to think that there my be an ECU problem.

When I manually test the fuel pump, it does make a bigh pitch sound that I don't remember.

Does anyone have any ideas of what I should check next?

Thanks in advance for any suggestions.

Don S.
