Default No spark on 929

I bought a 929 that had electrical problems and didnt start from the get go. I had to change the stator, battery, and rectifier. The fuelpump is priming and it is cranking but wont start so i pulled one of the coils out and checked for spark against the frame while starting it and no spark. I checked it with my volt meter also and nothing. I checked the ohms on all 4 coils and they were 1.3 but i dont know the specs..can anyone help? Thanks

Fuses all good?
Ignition switch with the diode all intact?

On the ignition switch. It sends a lowered voltage signal to the ecu as a security feature.
Do you have power at the coil plugs and injector plugs?
I trust you had a spark plug in the coil when you were checking for spark.

Check wiring harness for bad grounds, I had personal experience with one I was working on. Ended up having a rubb through the harness where it passes the fuel rail at the throttle body. It was getting pinched in between the frame and the big fuel banjo bolt. Put a eBay harness in, fired right up. Took forever to chase down because the rubb through was on the backside of what was visible on the harness, didn't find it till i had the harness entirely out, but don't sweat it only took 45 minutes all together it's pretty easy. But ya it was doing exactly what your describing.
