So you replaced the ECM because of why?

replaced the ecm because there was no spark. it wasnt until later that I realized it would spark after releasing the start button.

The problem sounds like the LR505 module.
It's a small switch module that controls the start stop function.
Or potentially the kill switch on the handle bars.
Get an ohm meter and under the handlebars disconnect the wire harness connector.
Test for ohms between the yellow/black wire and the black wire. with the tether not hooked up to the ski the reading should be 0.3 ohm or less.
Put the tether on the ski and the reading should be OL or no continuity.

If the tether is ok I would replace the LR505 module. It should be inside the electrical box and has several wires going to it.

I checked the module and it is out of spec. Thanks for the help. I had no idea they used a seperate module for the stop start circut.
