UL engine problem

I have a UL350iS that will not stay running.

A year ago, it ran great as I was getting ready for my air worthiness inspection.  I found a few problems that had to be repaired to include a few fuel leaks at the fuel tanks.  It took a while to solve those issues so it was 6 months are so that I did not run the engine.  Rolled it out to start.  Engine cranked, fired ran for 3 to 5 seconds and quit.

I have investigated everything that I can think of and it still does the same thing.

Any suggestions?  Has anyone used the UL Check software?

thanks,

Andy

I'd look at the last work done on the aircraft since the engine had last run.  If it was the fuel leaks, then start there.  Perhaps a simple matter of bleeding air out of the system.

Have you tried contacting Robert or Ray at ULPower with questions or for advice?

We have used the UL Check Software. If the ECU does not see running condition it will inhibit engine run. Ray Lawerence is the tech support in the US.kaolinaviation@gmail.com

Andy, what have you done for troubleshooting so far?

Did you ever get the UL Run problem figured out?

If you are running standard unleaded petrol it can leave a vanish like covering over fuel system parts blocking fuel feed .
