gt5-sr no spark

There is quite a few posts on this forum on how to trouble shoot the ignition system, I don't remember where they all are right off but if you do a search you should find info on this. The stickys on most all topics are there for you to read imbedded in them will be the info your looking for. No spark can be simple spark plug with too much gap or the plug is fowled out. Possibly you may have a bad connection or broken wire/ soldered joint. The worse thing could be a failed coil or cdi. Then there's the ol kill switch that will fail causing the system to not work.
First thing will be an ohm meter to check the cdi and coil, then the wiring.
