[QUOTE="Mihalis fjr, post: 1296859, member: 28900"] If the cylinder identification sensor is bad,the engine is able to start and run.If the lean angle sensor is bad,it stops the fuel pump and injectors and not the sparks.A bad crankshaft senson can cause this symptom.. Here,the starter motor works,the injectors and pump works,but not spark.. I think that the ignition switch has two circuits,one for the starter motor and one for the ignition. Perhaps the ignition circuit is defective,but not sure.Happened to my other bike ΧΤΖ750,the starter motor turned the engine but no spark. A new ignition switch and the problem solved. Τhe strange thing is that no error codes appears in the display.. [/QUOTE]
