Rotax 912UL difficult starts sometimes.

Thank you Roger?

I confirmed no ignition spark this afternoon. 
I am sending the Electronic modules to be bench tested. 

All the best

Gino

This very same thing happened to me, and yes, it was intermittent. Both of my ignition modules were bad. Confirmed with the ice trick and by sending the modules to Lockwood. 2007 model year. Warning:  sit down when they tell you the price for these modules. 

Thank's for the head's up Robert 

I will sit down?

When and how much did you pay?

Good night

Gino

Update on my Pipistrel Sinus
"engine at times fails to start"

Just got my "Electronic Modules"report from Rotech Motor LTD in Vernon BC
Electronic Module dual failure. New ones will be shipped this afternoon. 

With some luck I might be flying this Friday?

Final update on Pipistrel Sinus
"engine at times fails to start"

Installed new Electronic Modules and tested engine. 
Engine runs like new. Test flight was uneventful ?

Thank you all for all your suggestions and huge thanks to Rotech Motor LTD. in Vernon BC Canada for all your assistance ?
